I have tried just about every user-generated review site (i.e. Yelp, Cork’d) there is and most suffer from the exact same problem. They don’t capture my thoughts and feelings about the product they want me to review when I’m having them.
When I get home from a good restaurant, I usually want to take a nap. I don’t want to have to sit down at a computer a remember the nuance of the wine that I drank and how creamy my rissotto was.
This is where Washington DC-based startup Thummit get’s it right. They’re a user-generated review site but they do a great job of using the mobile phone as a way to capture the users’ thoughts and feelings.
You can either send a text message to their SMS exchange number or you can use Twitter and say “@thummit”. Thummit can capture your twitter data.
The fact that it can grab Twitter I think is really smart. So, instead of me having to do something wholly new and different just for Thummit, like I have to do with Yelp, it uses my existing behavior. I would have tweeted regardless about whether or not I liked the restaurant. Why not send that data to Thummit and allow it to serve it in aggregate with others reviews?
Of course, other user-generated review sites are getting into the mobile game. The guys behind Living Social (also based in Washington, DC) have recently launched an iPhone app, which makes their app infinitely more useful. I like to try new beers and so when I’m at the bar I find myself consistently going to my iPhone to log the beer using their Brew Social.
Right now Thummit is in private beta. If you’re interested in trying it out, I’ll ask my friends the founders and maybe they’ll give me some invites. Let me know.

Hey Justin!
It was great meeting you last night. You social rockstar, you.
I’d be interested in signing up for the beta of Thummit. Sounds like fun.
