Let's be realistic about something ..
Web changes everyday, and catching up with whatever is trendy is a necessity, we cannot ignore Facebook because "it will go away as MySpace did", because, what if it doesn't? Same applies to twitter, to Google Plus, sadly, the forums that move along with the times are the ones that will survive.
I once say that the forum providers' responsibility is to care about this. In this case, vBulletin or XenForo are responsible for providing a hip and updated product, because, to tell the truth, that is why I am paying for it, so I don't have to worry about integration with whatever-is-cool-today, they should worry about building the connectors, I'll worry about building my community.
Does this mean adding stuff that is a trend, and deprecating it tomorrow? Well, sure, but that is how it works.
Now, vBulletin, they are terrible, they have little quality, the products barely work and they are going down the pit but at least .. they are trying
- They have a Facebook App
- And an Android App
- And a Mobile Style
- And a Facebook App
.. down in the department of going ahead with the times, they are doing the right thing, they are providing the tools that some people think they need. Even if Tapatalk does XenForo and ForumRunner too, that is not the same as having a dedicated App.
Even if XenForo looks ok in the iPhone (I use it all the time), it is not the same as a mobile app, a skin designed to be browsed using a mobile device. And it won't be the same as an iPad skin, designed to multitouch (I loose all the hovers and onMouseOver)
And... guess what? vBulletin is going to sell those, and they are going to make money. And a business is about making money. Sure, keeping your customers happy and being non-evil is good, but if you don't have money you are out of business. Period. XenForo does not have the luxury to say "those are not important" if there is a market for it.
Now, what is the market for a Facebook app? I have no idea, people with fat wallets, maybe. But vBulletin is right in the sense of keeping up with whatever people seem to want, and that is ok. And that is welcome. The only reason it had such bad reception is because their main product is filled with bugs.
Myself, I would probably not use it. I have enough trouble keeping my users on the site, promoting them to login through Facebook is like committing a long, painful suicide and watching my users go away little .. . by little .. little, by little. (you get the point)
There is some level of Facebook integration that would be useful, though. The new Facebook graph allows for user interactions, so, for example, an Application can define "post a thread" as an interaction, an anytime a user posts a thread, the people would see that in the news ticker (new in Facebook), user A posted a thread ... and they have to come to the forum to look at it. That I like.
Users need reminders to come back to the site, if I could message them, "hey, somebody answered to your thread", like the email notification (call it facebook notification), that would be cool, it would keep the people coming back.
So, to round up. vBulletin intentions: good. Concept: good. Implementation: really bad
Putting the page inside a frame and loading it inside Facebook .. that is lame
Wanting me to pay $99 for that .. ha!
