Oh and the reason I use "ace2" mods. I like the mods. I use "non-ace2" mods too :P I do peruse this forum the most, because it's the most active between all of the mod sites, and the community is excellent.
And while I don't wanna make a 'me too' post, you really summed up my reason for surfing these forums the most as well.
As a user, I don't really care what libraries my addons use, as long as they do what I need efficiently. I will admit that due to the convenience factor and discussion, I'll visit here looking for a mod before I go other places. However, that's really more due to a) thinking that playing with betas is fun; and b) I like to read the development discussions. At this point, there are a few authors whose addons I'd try regardless of function, unless it's something I obviously can't use at all (like a class-specific mod for a class that I don't play).
But in the end, it's about users and perception, and most users don't bother researching and educating themselves to find out if their perceptions are correct. That applies to many realms, not just addon libraries. Clad, I sincerely hope that you can beat the fanbois down.
