> >it's somewhere on tech/vc twitter... ?

I'll translate: "It was posted on Twitter by someone who typically posts on tech and VC topics, and/or who typically interacts on Twitter with other accounts active WRT those topics. "

Alternatively: " The link was recently retweeted by various accounts that are active participants in tech and VC discussions on Twitter. "

These interpretations are not mutually exclusive, of course.

Essentially, the pattern "X Twitter" is roughly equivalent to "The X-o-sphere" and similar formulations WRT weblogs, but a bit more straightforward.
