Yes, everyone, Twitter is still intermittent, on the web side anyway, and with a Russian botnet unleashing a DDoS on the service, it won’t be the last time that we see Twitter attacked. So why did Twitter go down, but other victims of the attacks stay up? We ask Tom Merritt of CNET, and Stuart Miles of Pocket-Lint.  Tom reminds us that Twitter is still a young company compared to Facebook, and especially when compared to Google. Those two larger, more experienced companies have set up systems to better deal with malicious bad-doers who'd wish them ill will. Stuart thinks we're going to have to start realizing that what happens in real life can happen online too. Cities get crowded, so sometimes when someone is commuting to work, they get stuck in traffic. The same thing can happen online, except without the cars and smog. What's your take? Did you learn anything from the great Twit-out of 2009? Sound off in the comments. Distributed by Tubemogul.
