I think you should have some minimum criteria and don't just ad any newcomer until they have a history of trades. I think it's a good idea to keep an updated list but only if it's kept clean with trusted agents and not filled with everyone wanting to get into the business.
That's what I intend to do.
escrow.ms's signature says that he will be out of town "starting on the 14th" and will not be able to provide escrow until after he gets back. It has actually said this for a while now and he hasn't been active on the forum as much recently (I think he has been working on a bitcoin related project), so I don't think he is actively available for escrow.
Also what criteria do you use to rank to rank escrows? It seems you are using how active they are on the forum, but wouldn't you say that their trust ratings might be more accurate?

this thread for a somewhat outdated (last updated ~4 months ago) list of escrow providers.
Yes, as an escrow myself I would suggest to the OP to rank the escrows in some sort of trust system - it would take some work but should make the list more accurate.
Someone with 0 trust attached may be just as trustworthy as someone with +100 green trust. Similarly, someone with 100+ green trust can be extremely shady and not trustworthy.
I won't be ranking by public trust levels but will continually update the "big 5" with the most used, trusted and known escrows. You have been added.
