It seems many are misguided that there is one project only to hack the PS3, this simply isn't the case as now others are getting involved.. which is really good news indeed.
Most of the PS3 Devs are busy with their own projects and have little time to get involved in others projects, while balancing life, jobs, education, family, etc in the mix.
In summary, when the lead PS3 Devs here have news/breakthroughs they will post on it as they always have... but during the time between their progress updates is when other projects are great for those who enjoy tinkering with the PS3.
Not that we know of yet... all this does is help those who haven't made it as far as you get up to speed pretty much.
Most projects aren't intended to be an "all-in-one" instant hack for the PS3, in actuality this one, the HDD data one, the PS3 Portal one, and several upcoming others are geared for experimenting on specific areas or for the interest of learning.
