Couldn't find much of an online presence for his work. He's on nitter here fyi:

Re-tweeting the likes of Jonathan Cook, Electronic Intifada, and even ML:

'Media Lens is a great resource and has been for many years - I first encountered you in the 2000s when working at BBC News Online. Your email complaints were always on target! Deserve a much more views now for sure.' ( https://nitter.net/martasser/status/2047753395142906316#m )

So definitely burned his bridges in the msm, I'd say! Good to see someone put their journalistic skill & training to good use for a change.

cheers,
