What's your web 2.0?

Web2.0 is all about web-based communities and services that make it easy for people to share and collaborate. There’s an old post from around a year ago by Think Vitamin where he reasons that social web apps are great and all, but casual users don’t have the time to use them. He then goes on to interview the founders of several social software startups and finds out that most of them don’t use more than five either.
Does that still hold true? I’m going to bug a bunch of people and try to find out. At the very least this should give some ideas about which apps are popular and help me discover some new ones.

What is Web 2.0?

• Web-based software
• You can create and modify your own data
• Some social-networking aspects (friends list, etc)

The Rules
Link to this post and the post of whoever tagged you.
Create a list of the web2.0 sites you use and categorize them from “daily use” to “weekly use” to “monthly use”. Include links to your accounts if you want so people can friend you.
Tag a bunch of people you want to join in.
Even if you haven’t been tagged yet, feel free to participate in the comments or to join in on the meme with your own blog.
