Don't make me wait: Web 2.0 sin #8
I'm no Guy Kawasaki, but here's a free bit of business advice: If you're trying to compete in a field with a half-dozen nearly identical products, don't make a potential customer wait. If it takes five minutes for that account activation email to show up, he'll have already wandered along and found a different service that does what he needs without the wait. Thirty seconds is too long. The vagaries of the world's email relays aside, if your service's SMTP server isn't lightning fast, get another one, or you've just a pile of impatient customers--and on the internet, they're all impatient.
