I have noticed a pretty significant delay (many hours) between the posting of an article in the original blog and seeing it on TOR at least for things like Krugman's blog). This is especially annoying for "big" blogs (like Krugman) where I want to get an early comment in, before inundation or even closing of comments. Please optimize this -- it is much worse than Google Reader was. If this requires more computing power, make it a premium feature -- if the price is reasonable ($2-5/mo?) and there are some other useful premium features (like faster opening of the article list), I will happily sign up to pay.
