To me Silentale sounds like it has massive potential. Like the best start ups it meets a very definite need and also has a very clear route to making money. If the technology works well Silentale could be huge.
The big winners include Spotify (hey the iPhone app is here), Moo (who make those ever so cools cards) and Mindcandy (cool multi player online games).
Here's a site that has great potential. Justbought.it combines everything that's regarded as cool on the web at the moment: Google Maps, social shopping and Twitter/Twitpics. Or according to the blurb, "it's a location based social shopping that allows you to share photos/tweets." On paper it sounds like a winning combination, a vertitable internet supergroup especially if you trust other people's recommendations when it comes to buying stuff (I don't). Just one problem. It's very difficult to get excited about it - yet.
Can Posterous tempt Twitter obsessives back to blogging?
