How many people have you stopped talking to since you joined this site?

Several. Can't remember exactly.
I've been here 10 years or more.
Put simply, after a bit of chat I've found I had nothing in common with them
and the conversation was going nowhere.
I have no interest unless it's long, deep, concise and meaningful.
Also, I don't understand text jargon
and the quality of grammar with some is so poor it can be hard to guess what they mean.
If I'm ending it, I do so politely,
but a few take offence anyway.

Nearly all people I have messaged with. I struggle with small talk. And if i get one word replies thats it conversation over for me. Plus i can be busy for days and not reply it is not intentional.

Plenty. Most times it's not intentional, we just drift apart. But I wouldn't mind connecting again. And then there were a few users I told out right, I didn't want to talk anymore

Probably most I have interacted with.

Think of it like those brief conversations we have with strangers in the street or wherever.
It is not that there is anything wrong, people just chat and then go about their day.

Even so, there's a few I still talk to on the semi-regular.

Many
People move on

That happens often. I'm either not deep, nor concise, nor meaningful enough at times, I guess. So what?

None intentionally. People drift apart. No ill will.

A few.
I blocked a close friend because they constantly put me down or were incredibly judgmental or would tell me I had no reason to feel how I did because my life wasnt as bad as theirs.
