It's complicated/convoluted enough to be for a tech crowd, and modern/shiny/complex enough to be a disgusting mess to someone coming from IRC. At least for me. Given more users and activity I still wouldn't like it.
I might be wrong, but maybe this whole mess with Freenode won't be a big deal in the end. IRC never held a particular promise of "privacy" for me, many channels are logged by some or most of their users, or even publicly online via some sites. As long as Freenode continues to work (in a technical sense), and mass migration of channels doesn't ensue, I see no point in stopping my use of it.
I desperately hope matrix (or discord, which I haven't yet tried, but don't have much hope for either) won't be the answer. Maybe a switch to OFTC is an option for some channels.
We will see.
