I've noticed quite a few threads asking for critiques of their "sales letter", "landing page", or "squeeze page" copy.
Then, after several people are kind enough to spend THEIR TIME giving helpful (and valid) comments, the OP comes back on and says something to the tune of:
"Gee, thanks for the comments about X, Y, or Z. I know I should have done something like that, but I just threw this page up in, like, 15 minutes/an hour/between American Idol commercials. So I know it needs a lot of work. But thanks anyway."
Frankly, I find this kind of post self-centered, rude, disrespectful, and grossly inconsiderate of other people's time.
If YOU can't be bothered to spend more than a few minutes "throwing" your copy on the page, please don't ask others to waste their time reviewng your lazy, half-assed attempt.
