Normally I don't mind people sending me press releases and notes about their work. I'm not as sensitive as some bloggers, because I'm constantly looking for content.
But don't send me an invitation to your private Beta, and tell me:
"As requested, here is your invite to join the _____.com Beta."
That makes you a liar and spammer.
1. Send me a note.
2. Tell me you read my blog or heard about me.
3. Tell me which blog you were reading
4. Don't send multiple invitations to the same address.
Is that too much to ask? You know who you are.
