My presence is much the same as yours, johnnywang. It depends on how things are at work. If I am executing long running queries, like I am today, then I spend more time here. I usually log in once a day or so. Sometimes from home at night, or on the weekends. I like to try to come by on Fridays to see what the religious argument of the week is in the CB. When I am here I usually spend at least an hour. I leave my Newest Nodes until I have at least scanned all of them to see if I've missed any interesting ones.
