If you avoid other entrepreneurs, then maybe you're hanging out with the wrong ones.
If you liken anyone promoting their own business to a street preacher, then perhaps you're the one missing the point.
As for me, I don't ask favors from anyone. I just build what they already need and have asked for. I love writing software and I love sharing it with those who are interested, including those next to me at Tech Breakfasts. I've sold lots of software and built lasting relationships and friendships this way.
So I thought I'd share that with OP, who seems to have a problem doing and enjoying it as much as I do. Your attitude and response does nothing to help him (or anyone for that matter).
