more on conference blogging

I have added my opinions in a comment to that posting.

In general, I think discover-using-tag is more in keeping with the decentralized nature of the Internet.
It then becomes a matter of whether you accept all the tagged blogs/postings, or have a filter so that you can weed out tagspam, as well as whether you have additional mechanisms (broader searches, a blog/posting submission mechanism) to add additional untagged/undiscovered blogs/postings to the unified conference blogging stream.
