As my kids would say: "Really?"
Now, if I query you, I have to not only follow you on Twitter, but I'll be forced to wade through your tweets about what you ate for breakfast and what color you've decided to polish your nails this week to see if I made the cut or not? You're sooooo busy, your assistant can't take the time to drop the standard rejection letter in the mail box (or send the standard rejection email)?
Guess what, honey. If you're that busy with Twitter, you don't have time for new clients. I'll just happily take my business elsewhere.
