Haha I've never thought of myself as a space analyser :) I think the tool has great potential and I'm very likely to be a big fan - I've written a bit more about it on my blog here: TweetNotes - tool for archiving hashtagged tweets at events and conferences etc http://brodiesnotes.blogspot.com/2010/04/tweetnotes-tool-for-archiving.html

I've written a few posts on using hashtags at events, including ways of keeping the hashtagged stream of tweets after the event. In order of decreasing relevance... :) 1. Following conference hashtag tweets in real time and saving them for later http://brodiesnotes.blogspot.com/2010/01/following-conference-hashtag-tweets-in.html 2. Curated posts: liveblogging science conferences - my thoughts on tweeting medical research charity conferences http://brodiesnotes.blogspot.com/2010/02/curated-posts-liveblogging-science.html (a collection of posts from others, with my comments) 3. Health charity conferences: policy thoughts on liveblogging http://brodiesnotes.blogspot.com/2010/01/health-charity-conferences-policy.html (from the perspective of hosting a conference where new health research info may be presented, and how to handle its dissemination appropriately)
