Happy Friday! To wrap up the past week, we thought we’d offer a wee list of our favourite finds on Twitter this past week:

Last February, we predicted that Twitter would become more important to Digg and its Diggers. Behold! Our prediction has become reality! However, little could we foresee how tightly the two services would become intertwined. Now it seems if you Digg, you absolutely have to tweet.

Here at Invoke, many of us are Star Trek fans at heart. Watching its rebirth this weekend, we were struck by its fresh approach, yet respectful nod to the “old” universe, and the casting was spot on. But it made us ask: if we could recast Star Trek with social media personalities, who would be who?

On Twitter, the retweet is emerging as the best indicator of relevance for users of the service.

Whereas successful community-building used to be about getting followers, the realization is dawning that big numbers do not guarantee mindshare. Thanks to myriads of mass follow tools available, the power of a massive following has diminished. At present, retweets are the best barometer for assessing one’s value on Twitter…

For both current and former Digg members, there has been a marked trend towards establishing a presence on Twitter. Some experienced “Diggers,” a commonly used term for those that use Digg, argue that a Digg account is no longer complete without a Twitter account.
