If anyone can remember the old bulletin board software wars from years ago, you would remember an old major player called ikonboard. This software was a phpBB, UBB and vBulletin rival back in the day. But after they got purchased by a bigger company they lost alot of their users when the old developers of ikonboard broke away and created invision power board. Shortly after ikonboard became pretty obsolete.
Now the same thing is happening with vBulletin. vBulletin was purchased by Internet Brands and became more commercial and money hungry. The main developers of vB left the company and just recently announced that they are making a new forum software called xenforo. Which can be found at http://xenforo.com/
Could this possibly be history repeating itself? Will xenforo replace vbulletin in the near future just like invision power board replaced ikonboard? Only time will tell.
