Ask YC: Feedback on my webapp (semantic social bookmarking tool)

Faviki is a social bookmarking tool which allows people to tag webpages they want to remember with Wikipedia terms.

Unlike classic tags, which are just words, "Wikipedia tags" represent references to unique concepts that have their own URL. So, instead of having different tags for the same concept, which is the case with classic tags (cocacola, coca-cola, coca+cola, CocaCola) there are just the one unique “Coca-Cola” tag everybody uses.

You can register or just sign in as demo/demo and try it with bookmarklet.

The webapp is still in beta, but I just wanted valuable feedback from the YC community to help in next iterations. Thanks!

1. Interface. Is there any way to rewrite it so that the user can just add tags naturally, and then let the program make suggestions? It's a bit frustrating to wait, after each term, for the program to search for the corresponding tag. If you could input your own tags, and then it could list an official suggestion beside each typed term, I think that might increase usability.

2. Very minor point, but the demo video should be easier to find. I could be alone in this, but I always try to poke around for one as the easiest way to quickly grasp a web app, and the link was buried at the bottom of the page.

Seems like a great app, though; the complete lack of structure for Delicious tags was always one of the things that stressed me about it.
