Online, you are more likely to find communities of shared interest. Fans of a particular band, especially an obscure one, or practitioners of a particulary obscure artform, or whatever may be more likely to find others with the same interest online than in their real world community.
The likelihood of finding people with niche interests is almost negligible - there is a veritable graveyard of monstrous proportions of sites that have attempted to cater for such niche groups. Even common interest groups are less likely to thrive in a forum based online theatre over the banalities of Social Media. There are exceptions, but they are finite and even they struggle to maintain momentum.
I agree that online people have more chance to extend their spheres of interest and meet, even if just virtually, those they would otherwise never know they existed, but it is as you know well yourself how difficult it is to generate interest in those who would benefit greatly from joining an online community that catered to their interests and needs. People gravitate to where others gravitate to, which is why Social Media is such an attraction. I Skype my friend in the USA twice a week and it's great that we can actually interact face-to-face, far more rewarding than communicating with just the written word. I find that facility more remarkable and rewarding than forums or Social Media.
During one of our weekly debates he pointed me towards something interesting that could, in some people's minds, lead to conspiracy theories but where the two protagonists intersect is thought provoking to say the least. What he pointed out was LifeLog a project of DARPA to collect information on everyone, everywhere it ended in
February 2004. Nothing nefarious about that in many ways (though there would be concerns surrounding data protection) but what was remarkable was what he pointed out next. Facebook! When did Facebook come online?
February 2004. Coincidence? Perhaps.
Of course, I'm digressing, but I believe it was worth pointing out. If you get everyone together in one place you have the ability to exert control more easily, when people are divergent there is less ability to control. Now whether the inception of Social Media was a coordinated attempt to exert control is up for debate, but it's presence is not. I point this out because of the graveyard of sites that wanted to be separate and different, but are now defunct. So, the ability for people with diverse needs to express their uniqueness is watered down to the point where its existence is of no importance. I find that not only sad, but troubling because choice is slowly being removed.
This can be reflected in the diminishing act of socialising outside of Social Media control. When was the last time you had neighbours around for dinner, or a BBQ or any kind of social gathering without the need for an excuse, such as a public holiday? If you did, was it your immediate neighbours next door, or did your invitation extend beyond these boundaries? When was the last time you invited someone from your workplace around to your home for some general socialising? If you did were either of these one-off events or do you make a regular date for the invites? When was the last time neighbours or workmates invited you to their homes? Now extend this to your neighbourhoods and tell me whether there are regular days, evenings, nights when the whole neighbourhood can come together?
I'm not deriding the technologies that can bring people together (such as this site) but rather the implementation of that technology and the impact it is having on people's lives - particularly those aspects that they may not even realise are having an impact. People are slowly losing the ability to create real communities outside of their electronic worlds, and those that do manage to maintain a semblance of community spirit are in the older generational league and when they cease to be those communities they value may also cease to be.
We live in strange and challenging times on various levels and we need to be mindful of what is happening around us. The Churches are losing ground, belief in God is losing ground, belief in thriving communities who gather together and share time with each other, is losing ground. So much is being eroded and because it is a gradual process it tends to be invisible. The least violent method of exerting control is attrition, something to think about.
