You're offended by that?

Have you ever founded a company and tried to find paying customers?

You'd probably be offended if I sent you a cute 90's era AOL CD with our software on it.

OP: I wouldn't be offended if you emailed me in this way. Ignore the naysayers. This is perfectly kosher.

In fact, I'm going to check out your company in depth just because of this pearl clutching.

Keep building and don't let naysayers tear you down over something not even slightly evil. (Venomous attacks are more evil than this, frankly.)
