Last year specifically I've seen things being more or less 'ripped apart' from each other (a well respected moderator leaving, other developers within the community leaving, the community itself shaking, development halted and a noticeable missing of the previous clear and transparent communication towards the supporting community).
I for one do not wish to put everything on the -albeit appalling and shamefully unethical- lawsuit that was fired by Internet Brands. When it all started I was shocked and angry to the bone... mind you I am still feeling this... and I was truly impressed by the way this burden was handled by Xenforo (Kier in specifically) in public. Still, as of lately, there's also some mixed feelings arising in me, triggered by the things I mention in my 2nd paragraph above (cause not everything is only related to 'IB'). I don't know what to think of it all... but it does make me feel insecure, as a paying customer who wants to take his (vB 3.x powered) forum to the next (read: Xenforo) level, now and in the future. And obviously I am not alone in this.
Since I became a vBulletin customer in 2001 I have supported it's product and community passionately, because I believed it was just ace (up until the 3.6 version, and we know what happened after that) and I could contribute to improve the product. The same I felt when Xenforo saw the light of day. Seriously, for me it was like a savior being born, because XenForo gave me the means to escape from Internet Brands' outrageous way of handling a product and people.
Well... to make a (typical) long story short for once: I truly wish for Xenforo as a whole, meaning: the developers -both personally and professionally-, the product itself, the third party developers, the moderators, the community, that 2013 can and will be a bright and light year of unity. Internet Brands shows the worlds how not to unite people, so let's make sure then that 'we' do not fall into this same behavior/situation... and make this a place of what it set out to be: a product and place based on love (connection).
What I wish for 2013 is that Xenforo reconnects itself on all bases (whenever possible) and becomes the huge success that it deserves to be.
