Grishka: You have hit on something that has always (mildly) annoyed me: that phrase "thank you in advance." I always assumed people put that in to save themselves the trouble of thanking me (or whoever) afterwards.

The people who say that often have no idea how much work it might be to find an answer to their question, or how complicated the answer might be, or how you might end up posting only a tentative or partial answer, without knowing for certain whether you have given what was really wanted, and so on.

Not that it matters a whole lot; I will often undertake to answer a request only because I enjoy the challenge, or because I enjoy the thought that I am helping to build the world's biggest database of information about songs, which may well be here in some form for decades to come.

Still, it's nice to have one's work acknowledged.

I think some people post requests and then forget about them, and never come back to see the replies.

It's nice to know that that didn't happen. "Thank you in advance" doesn't supply that kind of information.
