Yes, I also thought about XING (http://www.xing.com) here in Germany. Many people say it's just a copycat of LinkedIn, but in my opinion they have created a much better business network than LinkedIn. And: they're profitable. Their business model ("Freemium") worked out and they've sucessfully expanded in other European countries and China.

I was not sure whether to post it or not. I am still not sure. It's not because I am afraid other people will be interested in this idea (ok, maybe a little bit), but maybe it will bring some bias in the conversation. But I agree that knowing my idea and knowing the competitor would help to assess the situation.

Yes, I think so. Like I said, it is not exactly executed like I would've done it. However, I am worried about the edge they already have in terms of being in the market already. Since it is a market with strong network effects (like many web apps) it will be hard to convince existing users to change services.

The problem is that in most of the cases you can't tell whether a service/website is worth this one-time $5 fee. I myself have to use a service for a while to decide whether I want to pay for it or not.

Wow, thanks for taking the time for such a comprehensive response/advice. I appreciate. Actually I talked to a few programmers already and no one ever has given me the advice to start with SQL. However, it seems reasonable to me.

Is it me or are some songs very difficult in easy mode? ;) I also think that there are some bugs in the key response. Or: I just suck at playing it. However, great idea and good luck!
