I'm sick and tired of facebook errors. "wall not currently available", site server timing out etc. I would estimate that 2%-4% of the time, I get a site error on facebook.
facebook has claimed to be a software company but with the amount of errors in processing requests to the site () I don't see how they can gain more traction as a "software company". The site has so much potential, but they really ought to get the site errors in check, quickly.
