I've never been in a chat room. They're impossible for me to follow. What is A/S/L?
For the truly lonely person, or the loner, it seems that people seek one of two things, or both.
Some, on one side, seek to know they're not alone in the universe. It's not alone as in nobody is there but alone as in, "are there any people/any one person out there similar to me." To discover that is a validation and it's enough. If this is the case then anonymous or somewhat anonymous conversations are perfectly fine. To seek validation only allows the seeker to stay mostly hidden behind user names and so forth. They don't seek and don't expect more than the occasional diversionary assurance that they share the planet with someone similar to them.
On the other side there are those who want and/or need more than just knowing someone is "out there." The law of averages says there must be, even if they're rare. But knowing isn't enough. These folks seek personal interaction, friendship, with one or a few people, people they can get to know, talk closely with, and maybe visit or spend time with on occasion. They're not so much loners by choice but lonely because of situations and circumstances and/or their particular personality quirks. To them chats with people behind masks, people who might or might not be who they seem, seems rather empty.
I fall into the second group. I've "done my time" piddling around online. I've had both kinds of interactions, personal and anonymous. Even though I have spent way too much of my time online, and still wind up doing that, I am a real world kind of person. I'm often only on here because there's not something to occupy my time elsewhere or my crochety old main frame is aching and tired from outside work. I enjoy interacting on the forum, discussing things, but my goal is to find that person or few people with whom I can develop a closer friendship. I don't like being alone and without someone to talk with.
So, whatever floats your boat. Personally, I don't so much like going fishing if I don't have a fishing partner. Get my meanin'?
