From the previous question:

As you may have seen from the front page, the site's been going for two years now. I probably spent a year on and off developing it beforehand, though many of the existing features were made post-launch.

I did make the site myself - it started as a side project while at uni for a web & digital media development degree.

This question has been answered already, but for the part that wasn't, it was paarthurnax himself

Thanks

Probably a long time.
