  In your blog post you mention OTR does DH on the 1536bit prime group. 
It looks like you swapped it in the comparison table.
  Same goes for the Proof of Communication.

  Also, you confuse two different concepts of authentication:
  Every OTR session uses cryptographic authentication. If you previously 
marked a key as trusted (ie. you know it belongs to the reported owner), 
OTR will flag it as trusted again if you come back later to the same DSA 
key.
  Claiming that torchat had automatic authentication while OTR used 
manual authentication is misleading, because the same manual 
authentication appears in torchat by exchanging the hidden service 
address (see Gregory's post).
