A lot of people feel very alienated by this lowest common denominator standard of the web and the fact that niche sites are dying even in absolute terms. Hopefully we will see a revival, when more people realise they were better off before this over-sharing nonsense. People adapt more easily to a lower standard than to a higher one, though.
I'm not claiming that my startup in particular will be it, but something like it. Just saying this probably puts me in the category of "just another young whipper snapper who aspires to be the next Zuck"... but I have no desire to do anything like Facebook or Google or intentionally copy any particular model. I just want to do what works (well).
Loggur is clearly an infant at this point and I'm sure the initial impression given by its current presentation of the idea doesn't exactly scream "innovation" or "the next big thing"... but bear with me. I'm starting off relatively simple and will iterate as I get feedback (as is expected of any startup) but the general end result, as I envision it, will essentially be an extremely wide variety of user-editable tools specific to each user and/or community, from communication to productivity and automation - or both. I realize that the current presentation is pretty vague, but that will change after iteration and solid examples. The current descriptions are based on an alpha version which I put together earlier this year to prove the concept.
It's called Reddit.
Bear with me here, I realize this is probably an unpopular opinion.
On Reddit, all content is open -- I don't think I've ever seen a 'closed' sub-reddit available only to members. I'm not sure it's even possible.
Yet, in spite of all communities being effectively open, most sub-reddits have a strong sense of community, and are very active. Personally, I really enjoy proggit and r/math for this reason -- active discussion, community moderation, and a strong sense of community.
I think part of what has happened to these dwindling forums is that they are functionally out-dated, and a bit too insular. -It takes too much time for new people to get up to speed on most boards. (dont forget Hubski, btw. :))
As for shutting it down: The code is open source, so while it'd be hard to unite around a common replacement, if they tried to shut it down it would not be the end.
The next time you hear the phrase "It doesn't scale" in reference to something, ask yourself why it needs to. In some cases it might not.
Centralised approaches (e.g. websites on the open internet) obviously need to scale. Facebook is a public website. And it's on the open internet, for anyone with an account to see and ready to be hacked by those with skill who do not need accounts.
I always come back to this: How many people do you really need to be reading your profile? Friends, coworkers, family, ... potentially anyone, anywhere in the world with a computer and an internet connection? It just does not make sense.
Communities before were usually separated by platforms, because the platforms were not yet sophisticated enough to support vast communities of varying opinions. Now we have a few big players that can do this and more. Social media has turned into a war over who can blow the most filter bubbles, and with services like OpenID and "connect with facebook", everything has slowly become part of the same identity.
I'm hoping that a new platform will eventually come along to pry this apart, but it's going to take a completely different paradigm to cause it. Unless something like Google+ proves otherwise, websites like Facebook and Twitter et al have the potential to monopolize social networking.
