Not only we. This forum is a pond removed from its old stream of fresh water, there are many such. First we get stagnant, then we start to stink, and finally we'll be overgrown by weed and dry out.
We are not the only ones to smell funny, decay is all around us. At this stage it is not too late to do something about it, we just don't know what.
I don't think there is any independent blog platform that is prospering. The antisocial social media are taking over, the prime maelstrom Facebook. My tagline for Google is The Lesser Evil, all they do is semi-open, while Facebook take as much as they can of human interaction and ingenuity and make it their property. The rest are mostly Facebook or Google wannabes (Twitter is a little more open than Google and at least some of the owners may regret that). Open alternatives haven't been able to establish themselves, traditional ones are succumbing one by one, Usenet, blogs, forums.
That blob of negativity was just to say that our stinky little pool is relatively fresh water, even when drying out. Closed and owned has gradually been replacing open and free (mind you many closed and owned ones have been sucked up as well). But if we continue as we do, there will not be a we when this forum is twice as old as now.
Most of the things we can do will increase the effort, not the longevity. I count an independent blog platform among them. If we could free human creativity first then recruiting more people to this forum should be easier.
