Twitter wasn't long enough for this experience.
So, I just got an email that I was about to respond to from an individual requesting a brief phone call; it was a business introduction; and it was very specific and sent to my apneicare.com email address. I realized after a moment that, oh, they probably got my email from a conference this past summer that I had given my name and email to for networking. Crap! That is why for usersfirst; I have two emails I give out--one for lists (petemail) and one for direct contact--so I can recognize the difference. I need to do that with apneicare.com also.
Here's some advice for email introductions, especially those requesting a phone call, please specify how you got someone's name in addition to why they might be interested in talking with you.
I'm still learning this Internet thing after 12 years of developing for it! I don't ever see it stopping--the learning this Internet thing--that is!
