I walked by 3com, Abbot Labs, WebMD (which had only 8 cars in the entire parking lot, at 2pm on a Tuesday) and several other tech companies I recognized. The utter lack of foot traffic and quality of personal transportation (ie, BMW's everywhere) was kind of weird, but to be expected in a big ass tech park.
Meanwhile, I'm here in the main 'sit around and drink coffee and bath in 802.11b radiation' with about 100 other people. In some cases the folks sitting at tables of 10 are talking, at others is silence only broken by keyboard clacking. Time to go to the first keynote by Howard Rheingold.
