Yes webloginPE is a great snippet (and we have a Polls module too), though it’s not without it’s problems... From what I have gathered, it won’t be that hard to modify existing snippets and resources to Revolution (it shouldn’t be a complete rewrite). And I think there is (or will be) an upgrade path with a script to jump to Revolution.
I might be wrong but I really think Revolution might boost the development of addons, since it’s more of a framework than 0.9.x was, and that should open many doors and speed up development. If Revolution reaches a "critical mass" of developpers joining during beta, we could end up with as many addons for Revolution by the end of next year that we have for 0.9.x (call me an enthusiast / optimist
but I really wish this happens and also think this is the key aspect we should put our efforts on. Revo’s documentation is a testimony that things are on the right path. Activity in revo’s forums is a nice indicator too).
Now it sure would be nice to have a native forum for 0.9.x / Evolution too, but I’d favor doing it for Revolution and make a case study of it and turn it into a promotionnal asset
If resources are sufficient, let’s do it for 0.9.x and port it to Revo but I think building it with Revolution would give more room to an innovative solution (then again, pure speculation on my part since I am no dev).
