The very first zevenseas solution by my mate Daniel is publicly available as a beta for you to download. Now let me indulge you in the history of the solution.. First of all it was called ShareMark and while the name isn't that bad, it was not meant to actually share Mark but rather a bookmark. So hence the name "Tagged Links" ;) Secondly it got Daniel to learn C# and leaving his beloved VB.NET behind him (still amazed me that even working at Microsoft you could get away only knowing VB ;). And thirdly, like I said in the beginning of the post, this is the first real solution of zevenseas! Expect more (elegant, flexible, dreamy, topnotch, etc) solutions coming from us ;)

btw.. the thing that impressed me most was the view with the statistics and the tagcloud (as seen in the image below)
