Nice, I wasn't aware someone in Slovakia actually knows about YC!
My 2 cents on cyclone:
Don't display the avatar/photo on the Recent post page - it is distracting. Also, display more than just 3 recent posts (on one page without scrolling) - in other words, get rid of the photo.
The "comments" and "edit" links are way to much on the right - I'm lazy, I don't want to move my mouse so far away :)
If you think of it, a user can submit an post with a URL and also additional links in the message body. This post would look confusing. Maybe you could scan the message body for URLs after submitting if the Link field is empty (to create anchors) or don't even bother at all. Oh, and you're missing the "edit" link in slovak translation...
Do you plan to deploy it oneday? Or is it just an exercise?
