I agree that I usually post tutorials about what I do on my personnal blog, but there might be some things I consider "trivial" that other people have difficulties to sort out.

For example, one might ask "How do I test different fonts on my system?". This is not a big task, but all the xset/mkfontdir and friends might be a little hard to get at first. So anyone knowing how to use it could write a quick tutorial, perhaps in the appropriate section on the forum so it can be referred to afterwards.

Just an idea though. Maybe having a dedicated thread like "Not-so-dumb question" could help
