Hulu lost me when they began actively blocking Hulu.com from anything that isn't a desktop/laptop. My Android device has flash, but they disable their site if you aren't on hardware that has their blessing. I'd still see all the ads, so why make your customer's life more difficult?
I think it really depends on your market. Sites like Facebook or Flickr depend on having a huge community, so offering free accounts makes sense. Others, such as the one described in the article, are hurt by all the resources it takes to support the free users when those resources really should be used to draw in more paying customers. Like all business models, I think you just have to ask your self if the freemium model is a good fit for your current product or not.
Because you only have 2 eggs I don't think you can use a binary search algorithm (assuming I understood the question correctly). I think you'd have to start at floor 2, if that passed then jump to floor 4, etc. until you have an egg break (lets call this floor n). Then, you go to the floor below the one that broke the egg to see if an egg survives that drop. You'll then know, using only 2 eggs the highest floor you could drop from without breaking an egg (either n, n-1, or n-2).
I don't wanna read your posts no more, you empty-headed animal food-trough wiper! I fart in your general direction! Your mother was a hamster and your father smelt of elderberries!
How (if at all) did you handle marketing your app? I have a few small Android apps in the works and one on the market, but gaining visibility is my biggest issue.
