    I think the risk to twitter is significant from spammers and MLMrs. I think the risk to Twitter is that spammers/phishers/MLMrs etc. are motivated to invest in trying to hack the site to spam it.

    Matt, I hope you continue to do this video tutorials. This one was very helpful especially about black hats and trying to think like them. As for renewing domain names, I can relate to that. One of my first clients neglected to renew his domain and afterward couldn’t retrieve it. It wasn’t just the PageRank he lost, but all the print advertising and yellow page ads that pointed to the site that no longer existed.
