Hello to all from me too. I'm not posting to get the first post done. 
Anyway, I just got my first Arduino board couple days ago and it seems really nice. From some reason I haven't really noticed Arduino before last week, but when I was reading some article where it was mentioned and my curiosity made me to read a bit more about it, I could't do anything else than order one.
If anyone's interested you can read a bit more from my development blog http://korvenmaa.net/arduino/ that I will be updating always when I have something to tell and time available to write some text.
I have a strong professional software development background from all kinds of environments, so I guess Arduino will be giving mostly challenges on the hardware side since I really cannot say that electronics would be my strong area of expertise. Probably this means that I will be posting some stupid questions at the electronics area pretty soon. 
So that's about it. Let's have some fun!
