If the primary concern about this boards future is related to monetary costs, why not shift it back to the usenet?
Usenet access is easily obtained through google or many other online sources, meaning people who only have web-browsers can still read/post, basic service is probably even bundled with most of your internet services at home. It is with mine.
All the benefits of the board could be realized(except for smilies, but I think we’d cope) in moderated usenet groups. And at little to no cost. A few people may have to bug their ISPs admin to add the groups, but simply charter up a few groups, cite costs of maintaining a web-based forum as the reason for their creation and I’m sure that most admins would carry them. Make them all moderated and have a “subscribe before you can post” rule where someone has to self-register their email address before they can post(cuts down on automated spammers), then let the regular mods do their thing.
alt.straight-dope.general-questions.moderated
alt.straight-dope.great-debates.moderated
alt.straight-dope.bbq-pit.moderated
alt.straight-dope.cafe-society.moderated
etc (the naming scheme doesn’t have to be this, can be anything, these are examples)
I wasn’t around when the transition was made from usenet to these boards, there may have been very good reasons for the web forums over usenet, but if we try again, learning from those experiences, and have moderated groups, do those reasons still hold?
If you turned the machine(s) running the SDMB into NNTP servers, we could all subscribe to those servers as news providers if we didn’t already have news feeds that would carry the groups and the current machines would probably last much longer/be easier to administrate. Being an NNTP server is much easier on a machine than being a webserver. A private news server would give as much control over who/what is posted as we have now. However, I still think moderated groups with a registration method would be sufficient.
If this wasn’t enough of a load reduction the groups could still be registered on the regular usenet so the load would be even more evenly distributed, with many posters/readers picking up feeds from their regular providers. Only those without newsfeeds would have to use the Chicago Reader’s news server.
I have left feedback that I would not pay to post. I don’t post often enough to get value out of it and I already subscribe to several web forums. I’d go back to lurking. I have also left feedback asking why transitioning the boards back to a usenet-based system wasn’t considered an option in Ed’s list.
