Ask HN: Review my startup, ClueMe

I use ClueMe to refresh things I want to know. For example, after reading on HN that there is a ISO-standard for storing sexes in a database, I made a short note that I repeat regularly.

All the entries in the global categories are questions, but around seventy percent of my personal entries are notes.

In addition to the general knowledge categories, I have made a group with HTML5 and CSS questions (under Groups->Programming).

If someone is inclined to check it out, I'd also be very happy to get some feedback on the admin part (requires login with a Google or Facebook account).

A special thanks to Natsu who designed my favicon and saved me £584 ;) (background: http://news.ycombinator.com/item?id=2176227) .

The address is http://www.clueme.net

UPDATE: I screwed up trying to cache the initial categories (The GO-buttons didn't work). Now it should be fixed.
