The key thing to overtly displaying your geek credentials is the software you use, the websites you visit – “digg is so 2005″ – and the podcasts you cite. (And if you have to ask what podcasts are, well, I’m making my point, right?) 

So, as if to test out the theory, I’m writing this post using flock. It’s a browser built on the Mozilla/Firefox platform which attempts to seemlessly link your browsing to some of the more popular next-generation (i.e. “Web 2.0”) sites, such as del.icio.us and Flickr. 

It’s still in beta, so it’s liable to break … but it’s quite nifty so far …
