If you don't mind my asking...
What is someone's motivation to vote on and/or discuss a deal? Maybe I'm missing something...
On the website itself:
1) It takes two clicks before I get to the deal. When I click on a deal, I go to a site on bargin-notify that lets me discuss/vote and I need to click on the same text again to get to best buy (or whatever). I think you should have a "buy this" button or something" on both the main page and the description page.
2) I think on the main page, you want to have a way to directly get to my searches. I'd imagine most people would come to the page and want to look at their searches right away. I could be wrong, but thats how I envision using it.
Overall, I like the idea of bargain aggregation. I'm curious how your getting commission off this if your just pulling data from RSS feeds, but no need to spill your secrets to us...
