I have been accused of being many things. One of the top names is "wet blanket" and this isn't just because of my crying jags or frequent enuresis. I don't look to round numbers as a cause for celebration. Each question is a valuable addition (does the number 7000 includes closed questions) and we shouldn't be looking to make one arbitrary number anything more interesting. Our fascination with number ending in 5, or 0 or anything else is more a psychological crutch than anything imbued with real meaning. The survival of this site and its well being should be measured in time, hits or mentions on other sites. Otherwise, we run the risk of encouraging poor questions to reach a supposed milestone.
I'll shut up now...
