Yellow,

I don't really understand K2 vs Easy Blog, RS Blog, any_other_blog.

I think K2 does everything that they do, but I might be wrong. Can anyone help me to understand the differences?

Is there a way for K2 to support pingbacks/trackbacks? This seems to be one difference that I have spotted, and it would seem a relevant feature, so I'd like to add it where possible.

easyblog have fully integrated the jomsocial community parts (activity, profile and comments ...) :whistle:

Hmm... yes that is interesting. It would be useful in some situations... if you're using Jomsocial but if you're not then probably not such a major feature.

Plus.... K2 seem like quite a decent set of people, perhaps they will introduce such a feature??
