I've enjoyed Hacker News the past year as I worked on KartMe, and now would greatly appreciate your thoughts on this free service for easily organizing and sharing favorite books, restaurants, gadgets, recipes and more. Thanks!
* What would get you to use KartMe every week?
* What would get you to tell a friend about KartMe today?
I wasn't able to understand really quickly what KartMe is offering. That's my biggest hurdle to either using it or telling people.
What would get me to use it would be something that makes it easier, faster, or cooler than tweeting, blogging, or however else I might let people know about this stuff. (Not that I actually do any of those things while working 12h days at a startup.)
Also: name issues. When I see "Kart" i'm thinking "shopping cart" or "mariokart" -- what's the relationship between that and sharing gadgets or recipes? For me at least, you've got a gap right there. The "K" for "C" substitution also gives me "KMart" associations, which probably isn't want you're going for.
I think your ideal tagline describes what you're doing and has a call to action.
Look at posterous -- currently "the dead simple place to post everything. just email us." Pretty wordy, there's really not much else to say about it. But it calls you to action.
Maybe you're "Share anything with your friends and save". Depends on where you want to take it.
