As Robert pointed out today, Twitter’s popularity is already leading some people to mimic the “business strategies” of cybersquatters. The Twitter account “powerseller“, for instance, is up for grabs on eBay, so far without much response but in these tweethappy times this will change for sure.

The question arises, though, if individuals and companies should run and register Twitter accounts for their names and domains, executives, blogs, products, and what have you, just in case they might need them for real at some point. Will Twitter grabbing become a viable business – or nuisance for that matter – so that it may become, in return, a business model for those protecting online identities?

It remains to be seen how far Twitter will go in terms of true mass popularity and sustainable use cases for companies, PR, individuals, self-marketers, bloggers and so on. But it made me think…and sign up for some additional accounts, just in case.
