UnionBook continues to pick up steam. Not only are the reviews uniformly good, but the numbers are steadily growing. We'll likely see 2,000 by next week.
A few groups, like the one created for members of the Canadian Union of Public Employees, are really booming. Ditto the Labour Films and Podcasting groups.
I have two favourites. The Pin/Badge Traders group is a reasonable size, but more importantly has already netted me a pile o'pins. Comrades in Australia and the UK have mailed me some and I had the pleasure of getting an American sister off to a flying start with a trader's starter kit.
Doing not nearly so well is a group I started, the Union Builders of Model Airplanes group. Two members, myself and an old friend and co-worker there with me out of pity I think.
Still, while I post mostly conversations with myself, there are some fine photos of recent projects available in the group's forum. And I must say the conversation is positively brilliant. :-)
