Glossary of Web 2.0 terms

Found this Glossary of Web 2.0 terms while searching for a definition of meme (missing from all other glossaries that I explored although that wasn’t many more than a handful).  I had a strong sense of the meaning from the way it has been used in posts, but I wanted to confirm.  I thought this resource might be useful, particularly for other “blogicini”, and Web 2.0 newbies like me.
