Aldon is right. I am behind the times. Although I prefer the slower, more meditative qualities of Metafilter to the fun, snappy collective-ADD vibe of Clipmarks. Maybe also, becuase I am an old, old man, I feel have already absorbed some of the info that might pop up here. Fainting goats are not news to me.
As is ALWAYS the case when you visit one of these blogs, visit the whole thing. Read some of the comments and get to know some of the requent posters/commenters. Who did this? Why? How does it work?
