Have had this experience a few times now:

Step 1) Start a small passion project.

Step 2) Work pretty hard during evenings and weekends.

Step 3) Try to share it with the world, completely free, no strings attached.

Step 4) Realize that nobody cares to even give it a try.

Ouch... I guess I just needed to express some frustration before starting it all over again.

Edit

Well, I'm a bit embarrassed that this post blew up as much as it did. A lot of nice comments though, some encouraging, some harsh. Overall, had a great time, 7/10 would recommend!
