About the recommendation that we create a new headline each time.
I might be wrong but
I wonder if it should be the other way around. Keep the same title, so author's don't get tricked into re-reading the same old pitch, and if someone likes your service they can go back and find it more easily. I change mine occasionally but not every week.
Good suggestion about the link in sig. Why did I never do that before?
It depends on what your heading is I guess.
Back on KB, I used to find I blanked out threads I saw continually, where the one photographer doing model shots who changed the title every single post to reflect the new shots, I clicked on every time.
Its comes too from author promo posts on KB, where the same books would be rebooted every week all at the same time, and it got puke worthy at times. No offense to the authors doing it if they're here, but I got so sick of it, the mods gave me a way of avoiding seeing them completely. So here I'd rather put in place a guideline which tries to keep things interesting.
At the same time though, if you're not rebooting regularly, I'll probably never notice if the heading got changed or not.
