As always, the proof is in the eating (Zoho)
I feel the last thing the growing jQuery community needed at this time was a significant communication and collaboration infrastructure downgrade.
I think the jQuery team talks a good game about "getting involved" but its really apparent, once one tries to do-so, that the collaboration infrastructure is not there (not just Zoho, but docs especially).
Combine one petulant public rant by @jresig with a rushed switch to Zoho without any objective criteria whatsoever, no input, no testing, no parallel operation, plus unilateral bridge-burning proclamations ("I will be closing this forum..."), and you pretty much end-up where we are.
Answering questions and following discussion is currently a nightmare. I cannot imagine answering 100-questions per month on Zoho. I think the jQuery team is going to have a tough-time recruiting and retaining help-at-large until the situation improves drastically, as opposed to improving glacially which would be a generous assessment of Zoho progress since the switch.
Notice something? Those who've so-far said they "love this forum" don't actually partake much beyond that.
Measure it, you'll see.
If you bother to measure the number of questions, number of answers, numbers participating, Q&A lag-time, and so on you will see it. If you don't have metrics, "spectacular failure" is only heard as "spectacular" or whatever you want to hear.
That is all I have to say about this rushed, unilateral and ill-advised switch to Zoho.
