a) we're legitimate curious visitors (albeit not maybe not customers - but who's to say that some of us wouldn't be converted from window shoppers to buyers - that's kind of the point of websites after all) and
b) her webserver set up to only allow for 500 concurrent connections. Which is just pathetic - particularly given the amount of crap she serves (and thus the countless number of additional server connections each visitor makes to download said content).
I used to think that her site was a mark of a genius; where she deliberately made her site to look amateurish to push the site viral and thus give her huge exposure that most other rentals could only dream of. But then I read her rage tweets[1] and realised that she's just another idiot with an internet connection. Needless to say I'm very disappointed - I liked Lin and her site better when I thought it was designed ironically.
