As far as the cracks go, they'll have little to no impact on their operaitons at all.
Also, many sites, especially ones that spread virally (social networking, some dating, and basically anything that revolves around interaction with others instead of just "tools") there is an uphill battle to get the first decent size batch of users. I think linkedin is a good example of this. It took a while for them to get enough users to make it worthwhile for most professionals (those outside the valley) to want to join it.
Delaware might charge more because of the simple fact that so many companies incorporate there. Finally, those "incorporate" services that charge a few grand basically give little advice and just fill the paper work out for you. They take advantage of the naive.
