Invites: Waiting for Godot?

As I have done on many previous occasions, I have asked for an invite today to get on Pownce, yet another social networking tool. I find it curious how the invitation systems work or don't. Sometimes, the invite comes, geez, almost before I click the submit button. Sometimes, they never come (like Orkut, which I finally signed up for today). Now mind, I am not a sign up for every new thing that requires an invite type person, although I do like to be an early trier (and adopter if I like it). I am though the kind of person who, if they really (really) likes something, I will use it, hype it, and share it with everyone I know. Conversely, if it sucks, I will let the world know that as well. So, I hope the good folks at Pownce see this and, if their product is up to it, will send me an invite. Oh, for those who are not dramatically inclined, the title reference is to Samuel Beckett's play in which the characters wait for someone who never arrives.
