In the UK I started and ran a site listing tech events: https://opentechcalendar.co.uk/index.php https://opentechcalendar.co.uk/index.php It's just had it's first birthday and is doing well. This was done in a "maybe-a-bit-to-lean" fashion. There was a previous facility run by a local meetup that suddenly stopped, so I knew there was demand before I started. The first version was a MediaWiki site with a hacked open source calendar plugin that took 4 days from buying the domain to public launch. This was then later replaced with custom software. This now picks up a small amount from direct sponsorship (as in, I directly approach ppl and don't use something like Google AdWords). It took a bit to write, but I've realised the specific niche functionality could serve others and I'm currently working on turning this into a platform for any area. It's early days for that, but it works and it's up at http://ican.hasacalendar.co.uk/ http://ican.hasacalendar.co.uk/ (I also have some recurring income supporting a freelance contract I did which now takes a couple of days per month but I don't think that's what most ppl here are interested in.)
