It's been a long time since S2 has been mentioned. S2 is not a currently 'active' project as far as BradFitz is concerned, but that doesn't mean I can't continue working on it since my name is in the little bubble too!
core.s2 is now essentially finished. Due to a couple of remaining compiler issues I can't actually compile and run it properly yet, so it's not been through testing and so forth, but the structure is there which means that it's now possible to build layers on top of it and be reasonably sure that the foundation isn't going to change too dramatically from this point forward. As far as I can tell, the design of the core layer is correct and ready, so it shouldn't change at all now unless Brad takes issue with the way I've done something.
At this point I'm the only person working on S2. Back when S2 was announced properly, a massive four people other than me said they wanted to be on the 'team'. Regardless of this, the time is almost here for S2 to become a team effort. All of the current system styles need to be ported to S2. The major problem with this right now is that only about four people actually know S2 the language and how S2 fits together, so what I'm going to aim to do is over the next week finish porting the Default LiveJournal style to S2 and write up a rough guide to what makes an S2 style tick. At that point, people can look at it and see if they fancy tackling the porting of one or more of the other styles to an S2 layout. I've actually picked the easiest one of the bunch for my example, because it has very little in the way of customisation options, but the others will have options like "Do you want the link bar on the left or right?" I'll go into this more later.
This post really has no purpose other than just saying "hey, S2 is moving again". If anyone has any questions about S2 feel free to post them in response to this and I'll do my best to answer. The only question I won't answer is "When will S2 be ready?" because I really have no idea... Brad's the head of the project, and S2's currently not active for him. I'm handling a small part of it currently, although I might expand later if Brad releases what he's done so far regarding the customisation interface. (Anything?)
