I agree that many people here haven't launched in a public way. We (
http://strongsteam.com/ ) have some closed alpha users and add more every few weeks, we'll be months before hitting beta. There
are however a nice set (10%?) who have launched and may not be in @jot's page, some are physical products (e.g. photo booths for bars, waste water boilers->clean water, human waste sanitisers) which don't appear on the list. There's quite a mixed set out here which makes for very across-the-board conversation.
