Probably. He just moved his blog off livejournal (http://bramcohen.livejournal.com/) where you can find his older entries (ideally he would include a link to that on the new site.) He also frequently creates public posts on Facebook (http://www.facebook.com/bram.cohen).

He was blogging (not very frequently) at http://bramcohen.livejournal.com/. Now he is blogging (not very frequently) at the site above.

Looks like he may have done some cleaning. I noticed he doesn't seem to own bitconjurer dot org anymore, maybe this is why?

I still own bitconjurer.org, there's a misconfiguration of some kind which needs to be tracked down.
