If it's OK, I'd like to add my two cents to the thread as one of the noobs. This may be a bit long.
I lurked here for a few months before joining, trying to get a feel for the forum and whatnot. I'll admit that the barriers to registration contributed to that in no small measure, but that wasn't a huge deal because I could read things and be entertained.
As noted, this site has a fairly unique culture which has pros and cons to it.
On the plus side, I really have to say I enjoy the no-bullshit policies combined with the emphasis (in most forums) on rationalism and critical thinking. I can't say how welcome that is, given that this is, well, the Internet.
I don't get my news exclusively from here, but I do make it a point to check N&P regularly just to make sure I don't miss anything and to get the (inevitably funny) commentary. I enjoy the OSF discussions, most of the SLAM discussions (the ones I can understand, sadly advanced math goes right over my head), and a few other sections.
However all of this comes with a price; this board is very unfriendly to new posters. I haven't experienced that personally (yet) because I knew what to expect coming in; that is, I read the rules and got a feel for the place beforehand.
That said, I do notice that I'm very hesitant to post and do make every attempt to think through and word my posts carefully, lest I "slip up". Some would argue that this is a good thing, and maybe it is, in the scheme of things.
The flip side of that is that not everyone is going to do those things. If you open the site to
The Internet, you're going to inevitably have to accept some degree of slippage, as far as quality goes, on that front.
Further, and this is something I've noticed both as a pure lurker and a member, there does seem to be an incongruity between the site's heavy-handed rules and how those rules are enforced. SDN has, by far, the most iron-clad set of rules, procedures, policies, and quasi-bureaucratic enforcement I've ever seen on a web forum.
It's not my place to criticize that, nor would I anyway, because I don't think that's necessarily a bad thing in and of itself. I do feel that it is worth pointing out, because for one, members that might otherwise contribute can be very turned off by what can seem like overbearing emphasis on moderation/administration, vs. emphasis on encouraging discussion.
In addition, just from what I've seen, this can lead to the appearance of favoritism or more general unfairness when these rules are enforced asymmetrically, as when elder members are given leeway as compared to someone with a newer join date or lesser post count.
I do understand the historical context of these rules, in light of this place being a hard debate forum and given the expected dishonest debate that would ensue. That said, it has to be acknowledged that this state of being, to include both the rule-set and the culture that surrounds it, is a major factor in keeping away new joins. Why deal with it when they can just go to another board and not deal with what seems like taking the Internet way too seriously?
Ultimately I think that the board's direction will have to be decided on before any policy changes can be made, or even defined clearly. If SDN wants to remain a smaller community with a premium on content quality, even at the cost of membership and traffic, then I don't think much needs to change.
If the board does want to change direction, then it would be worth looking at a larger paradigm shift, and I'm talking very broad strokes. Changing the registration policy would be a big start. I agree with the side that feels the lockdown is a bit of an overreaction. The Internet is full of dumb, and turning into a fortress won't actually stop it, but it can harm the board in a general sense. It would seem that the numbers agree with that.
I don't know if phpBB has an Akismet plugin, but I've found it to be very useful on a few other forums. If not, simply suspending image/flash embedding is a good idea, and that can be done simply by assigning new registrations to a probationary user-group until N posts.
As far as board culture/rules/yelling policy, I don't really feel it's my place to suggest changes given my relative newbie-ness; I don't think that would be right of me to barge in and tell people how to do things. Instead, I will submit that I've seen many other forums operate just fine without the quasi-police state style of moderation here, and some of them can even maintain a high level of discourse. It may not be what this board is used to, mind, and that hands-off style may not even be compatible with this community, but I do point it out just for the sake of further discussion.
It's going to entirely depend on how much the board culture is willing to accept changes, and more importantly, what kind of changes the board culture wants.
Sorry for the long post, but I had quite a few things I wanted to add. Be gentle
