1) A site for hosting contests for the web app startups, one app at a time. Similar to AppSumo, but instead of selling the subscriptions (of web apps) at an insanely low price the new site will be hosting contests for distributing free subscriptions to the contest winners along with the regular discount coupons. It will be a good way to distribute the invite codes for startups and to get some buzz free of costs.
2) I myself felt a need for this. A shopping search engine for ebooks from Amazon (Kindle), Barnes & Noble (Nook), Borders (Kobo) etc. I use all three ebook readers in my iPhone and felt a need to search all 3 to find the lowest price for buying. Should it be a website or an iPhone App?
Which one should I start & would you be interested in as user for them?
