Furthur is not a band that is going to be around much longer (<2 more years).
Furthur was not assembled to become a commercial success, or grow a giant fan base. It was based more on musicianship and sharing that music with others. I'm sure Bob and Phil did not want to create another monster ala the GOGD in the 90's.
Management of Furthur is the worst part of Bob and Phil's job. Remember how much the members of the GD disliked business meetings, and how the decision making caused discourse between the members. They don't want to mess with anything other than the music.
This entire site will probably be shut down within a year after Furthur stops playing.
Why invest in new servers and promote building a "Furthur" fan base when it's going to be so short lived.
It's kinda like the successful small business owner that is close to retirement, and isn't going to sell it. They can afford to go old school, not worry about the competition or advertising, keep it simple, even at the cost of lower sales. Pissed off that they aren't open on Saturdays? Well, they don't have to be open, and they like to enjoy their Saturdays. They can relax with the comfort that the long time customers that they have built up over the years will sustain their business until they finally retire.
Not being able to get on the forum reminds be of getting a constant busy signal on the GOGD's hotline phone # trying to get tour info. Oh well, that's life.
