If you use it, I urge you to use twitterfeed with tact. Otherwise, your followers will tire of the twitterfeed spam and stop following you, thereby branding you a stinker and an insensitive spammer. This is the exact reason I stopped following Godin. But if used moderately, I think there’s a place for it.
I would say: use Godin as an example of what not to do, then promote your wares accordingly. (I know I’m going to get my car keyed by saying ‘don’t do as Godin does’, but hey.)
