Thank you! It depends on what you mean by "often", I guess often enough. I use Pastery all the time (especially the editor plugins), and all my developer friends love it too.

I guess people use some of the other services too, for example I get lots of comments for Spamnesty. I don't really care enough to look, though, as I built them for myself or because I thought they'd be fun, or because I just wanted to make something with a friend.

I was just curious because many developers enjoy (and want) people to use the stuff they write.

I was just wondering if/how you tried to market it or show it to more people.

I mainly just post them around HN whenever the opportunity arises :P

For me its a bit of a balancing act... You produce a project which is successful means you need to devote time to it. But to devote time to it you need to provide support, updates, etc. If your projects doesn't earn money or you are forced to work on something else it becomes difficult and then you whish people will not use it. Most troublesome are student projects who pm you.
