I launched TikiToki Timeline Software (http://www.tiki-toki.com) in March. It is currently making about $250 a month from subscribers. This month I have also sold a $1500 single timeline license. Hopefully more of them in the future!

I am currently operating TikiToki as a side project from my main business as a freelance web developer. Aim to go full time with TikiToki at start of July.

This will be a bit of a gamble, given that what I earn from subscribers via TikiToki for a full month is less than what I would earn in half a day as a freelance developer!

We do it for love as much as the money!

Edit: If we want to go into detail, I should also add that I also earn about $80 a month from Adsense for a blog my wife and I run (http://www.casualgirlgamer.com) and about $25 a month via Big Fish's affiliates scheme. Peanuts really but it all adds up...
