Yes, A couple of my good friends recently persuaded me to publish my blog engine. I have kept it for myself up to now, as it was in my opinion missing key features, got some annoying bugs, not perfect.. and so on. Many of my projects reach this state and die in it.
So here it is at GitHub: https://github.com/tetryonreactor/mogblog/
I chose the ISC license for it. In my opinion a more free license than GPL. It is a freedom to be able to take the code, modify it and not have to publish the modified source code. The most free license is public domain, do whateva, but a little bit of vanity makes me choose ISC.
