I went with option 1 for this Thing; I was browsing through the list of archived webinars and saw a bunch on Booklist's site that might be handy.
Then I made the mistake of picking "Booklist Webinar—Beads, Bulbs, and Books Bringing Home and Garden into the Library video archive" for my webinar. That was dangerous. Easy to download, easy to install the player - and crap, I want a bunch of those books now.
I've attended webinars and online meetings before, and this one was definitely less participatory, judging by the archived recording; since it was focused on pitching books, there didn't seem to be places for viewer questions while it was live. As someone who still sometimes scrambles for places to find new titles, these archived webinars from Booklist could be quite useful. (They could be useful to me live, too, if there aren't time conflicts.)
