The interesting thing about all the forks is to find out what some of the most talented coders think is most necessary for and "SMF2-like thing".
Each of this forks is slightly different from the direction the team has taken working toward SMF 2.1.
But each of these ideas can have their effect on the development of smCore, which will be the basis for SMF 3.0 and related apps.
So, when you share your vision for the guts and/or appearance of BlocWeb, or a fork like eos or wedge, you can influence the future of SMF.
Not only that, with the change to the GIT repository, the SMF code is out there for all to see, and there will be the opportunity to contribute significantly to smCore and SMF3, as well as to the SMF 2 line, even from those who don't currently wish to join the SMF team.
It's a new way of working for SMF, but I think everyone is trying to get the hang of it.
