There has been a lot of news recently about various conventions, so here is a summary:
No news re: bascon (it returns in November 2007) but I missed this when it was posted last year: commentary from Sunday morning's Vid Review. [Of interest: a complete list of the vids in the 2006 vidshow, and a list of the vids in the vid party.]
The escapadecon vid show deadline is Friday, February 16. Also, Escapade Panel Suggestions are being accepted at the website, which usually includes at least one vid panel on the tech track. You need to log in to the site to submit panel topics, then use the "Suggest a Panel" link on the left sidebar.
