Thanks for taking time out to comment. As you say Unscatter seems a similar idea and we can see where you're coming from re: context. We hear you on the speed - this is what we are trying to focus on - make this a super quick, great user experience. You're right in that caching is the way to go - again it's one of those release early and iterate items. We don't presently do any caching as such so this is no doubt something we will iterate on. In terms of monetisation - for the first few months we are looking at adsense to get a feel for how contextual the ads are and what the relative click through rates will be. After this we have some ideas that we hope will work out well.
