I can see that it's sorted now, but I don't think I explained my intention well before. What I meant was the order should be something like:

- language

- sql

- webserver

- webframework

- sourcecontrol

...

- stuff most people don't use on their projects, like mapreduce and graph-store

Also, the tooltip definitions are helpful but it's not obvious that they are there. I only knew they were there because you said so here. :-)

Good luck!
