Useful readings to write your first filter

It would be great if there was a "My filter share" section, where newbies like me could post their newest creations, and were die-hard knowledged people could give hints and corrections, this way, the Proxomitron should bloom up again, since, as it seems now, after the vanishing of Sidki & Co. proxomitron is quite silenced, and more and more problematic sites/situations appear.
