Well, you could always insert the "watch my auction" on your ad, if you ask, then maybe they will.
Really tho, I think you just have to have a great story, funny, wacky, sad, weird, etc.
The diaper pin my friend put up had 2400 watchers by the time the auction was done. I'll be honest, I didn't even know what the pulse was until about 1/2 through that auction (we didn't do much research LOL).
