Vladimir has no doubt been extremely valuable for the magazine and it's sad to see him leave.
Let's not forget that the magazine consists of more than just 1 or 2 dudes, but a whole team commited to the idea of the magazine and working hard for that.
After having hung out with Mihai in London and afterwards in Sheffield for a couple of intense days (and nights, I can tell you) I can assure you he easily has what it takes to run this show. He's been the goto guy for the mags coordination and managment anyway, even back in the days when Mr. Wright was still part of the endeavour.
Mihai is in fact the creator of the magazine (see "Editor's Rant" in issue #4).
So rest assured, the mag is alive and kicking.
I'll repost here exactly what I posted on the other thread:
Exactly. It's not. Mihai may not be prominent on the forums, but he has been in fact the most important person in the magazine's production all the way from when the idea was first conceived last September, and I trust him in this business both in integrity and in competence completely. We have a strong team onboard with prominent members of the Bitcoin community participating, so the magazine will only get stronger.
Magazine is doing just fine, and is only going to get better from here.
