Blogs are being used in many secondary schools and colleges. They are used for a variety of purposes: authentic writing assignments, collaborative assignments, asynchronous class discussion...
Here are some links to blogging information and some academic blogs to get you started.

Tim O'Reilly wrote a piece on web 2.0 in 2005 that is illustrated by this mindmap created by Markus Angermeier. Read Tim's article
You will keep seeing this term "Web 2.0" but finding a clear definition of what it is or will be is tough. Easy answer: it is what the web is becoming and (unlike Web 1.2 or whatever might have been the next version) it will be significantly different from the web we know & use today.
In this second version of the web, the architecture and the applications of the web will change.
1) This web will be interactive beyond clicking links on a page. I believe many applications will be running online, data files will be stored online "in the cloud."
2) Collaboration will be recorded in this space too. This is the web as operating system or platform.
2) This new web will require new security functions that had not been really considered in 1.0 (though that's what we should have expected and I don't blame Sir Tim Berners-Lee).
3) Web 1.0 encouraged sharing and stealing of content. 2.0 will further all of that. I don't mean to say that is a good thing. It's a social aspect that will require changes in our definitions of terms like sharing, plagiarism, fair use, copyright, ownership in the private, commercial and legal worlds.
4) New economic models will emerge of how to use this web for commercial moneymaking purposes. Web 1.0 never saw that. Now it's obvious.
5) Internet2 is an attempt to create another web for education and research use, but the other players will also want that speed and be willing to pay for it. If they stay separated, the "commodity" internet may end up being faster, stronger and more cutting edge then the research web. As with most technology in education from K to 20, education will be playing with the old toys.
SOME WEB 2.0 APPLICATIONS and TOPICS TO EXPLORE

You've probably seen some TV news coverage or articles about forms of social computing. MySpace and Facebook have gotten a lot of ink and sound bites lately.
Take this excerpt from the Business Week December 2005 cover story
"Preeminent among these virtual hangouts is MySpace.com, whose membership has nearly quadrupled since January alone, to 40 million members. Youngsters log on so obsessively that MySpace ranked No. 15 on the entire U.S. Internet in terms of page hits in October, according to Nielsen//NetRatings. Millions also hang out at other up-and-coming networks such as Facebook.com, which connects college students, and Xanga.com, an agglomeration of shared blogs. A second tier of some 300 smaller sites, such as Buzz-Oven, Classface.com, and Photobucket.com, operate under -- and often inside or next to -- the larger ones. Although networks are still in their infancy, experts think they're already creating new forms of social behavior that blur the distinctions between online and real-world interactions..."
The complaints with MySpace (and other sites including Facebook) and high school & college students and pre-teens are much the same as fears that were voiced years ago about chat rooms and instant messaging.
There is a criminal probe into MySpace by the Connecticut Attorney following reports that a number of underage girls in that state were found to have had consensual sexual relations with adult males they'd

Folksonomy: folk + taxonomy - refers to the collaborative but informal way in which information is being categorized on the web. Users are encouraged to assign freely chosen keywords/tags to images or data. Most commonly found on sites that share photographs, personal libraries, bookmarks, and blogs which often allow tags for each entry.
You may be familiar with scientific classifications.
Do you recall studying the taxonomy of organisms? [Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species]
There are taxonomies that are not considered "scientific" because they include sociological factors. In academia, many of us know Bloom's Taxonomy - the classification of educational objectives and the theory of mastery learning.Non-scientific classification systems are referred to as folk taxonomies, but the academic community does not accept folksonomy into either area. In fact, some who support scientific taxonomies have dubbed folksonomies as fauxonomies.
Others see folksonomy as a part of the path to creating a semantic web. It's a web that contains computer-readable metadata that describes its content. This metadata (tags) allows for precision searching.
If you have ever tried to get a group of readers or graders to agree on how to evaluate writing using a rubric, you might understand how hard it would be to get the creators of web content tag content in a consistent and reliable way.
Some examples of standards for tagging include Dublin Core and the RSS file format used for podcasts (such as that used in iTunes). All of this really grew out of the use of XML. Extensible Markup Language (XML) is a general-purpose markup language (as is HTML) that was at least partially created to facilitate the sharing of data across different systems, particularly systems connected via the Internet.
Folksonomies do have advantages. They are user-generated and therefore easy (inexpensive) to implement. Metadata in a folksonomy (for example, the photo tags on Flickr.com) comes from individuals interacting with content not administrators at a distance. This type of taxonomy conveys information about the people who create the tags and a kind of user community portrait may emerge. Some sites allow you to then link to other content from like-minded taggers. (We have similar taste in photos or music, so let's check out each others links.) Users become engaged.
There are problems: idiosyncratic tagging that actually makes searches LESS precise. AndÂ polysemes & synonyms (words which have multiple related meanings) may be inferior to using some agreed-upon criteria.

I wasn't sure myself. It's the kind of question you need to ask some millennials.
So far, I have gotten these answers:
