My OpenGuide site, The Tourist Engineer is finally working again. Thanks to Kake for prodding and fixing the database format. That made all the difference!
The site is a tourist guide for geeks, looking at architectural marvels, giant infrastructure, geeky historical sites and the like.
I'll continue maintaining this site, but I'm also thinking of starting an Open Guide to Sydney, in the mould of London and Boston. These are open Wiki guides to cities, and when they work well they're absolutely brilliant. Sydney doesn't have much in the way of free, open guides to things. Most seem to be search-engine-harvesting "guides" with plain listings and no real opinion. There's nothing as good as the ever amazing Beer In The Evening. I think we need to harness some of this user-generated goodness for Sydney.
In the meantime, please check out The Tourist Engineer and feel free to jump in and add new sites.
