What's the longest project you've worked on (in a passage of time type measurement)?. Mine' s a client website, 2 years (so far) in the making. 1 complete redesign, and re-written vast chunks of CSS and code because some of it was shit (2 yrs ago). Now it's super efficient and looking good. Still not finished though. Fortunately they know it's their fault and they have paid up to date, we are at double the original estimate now. I have not moaned at them because they have not moaned at my charges.
