Infopop appears to have lost the mindshare battle against vB, IPB, and others. Since their new product will combine the features of Classic and Threads, it won't have nearly the same featureset of other forums, and Infopop may be months or years behind catching up.
There is no distinct price advantage for Infopop either, considering the free BBS's and the perpetual licenses (with free upgrades) their competitors offer.
That both Charles and Rick will be working on the new product does provide some hope. Charles always provided excellent support when we ran Classic, but Threads support has been lacking. The well-documented bungling of Threads releases over the past year is also very discouraging. Hopefully the 2 of them can achieve better results.
Subjectively, the communities surrounding competing products are much more vibrant and producing many more mods, skins, and hacks than the UBB communities. I am not trying to denigrate this community, but when I look at all of the sites supporting vB and IPB, it's staggering.
The splinter to FusionBB has personally left a bad taste.
We are going to convert to IPB. It was a tough decision, but what's lacking in Threads and the new product has forced us to go elsewhere (and we can't stand vB).
