I dabble across the network - and while IPS is for questions about the behaviors used when interacting with people towards specific outcomes - it's not about picking up social skills or a subset of them, or for sharing of anecdotal personal experiences. It's worth reading the entire help page, and not cherry picking from it.
Of course - I'm going to cherry pick a little bit, and quote:
Questions focusing on using and improving your own interpersonal skills, in an attempt to resolve specific problems or prevent problems from occurring when having specific interactions with people. A list of what to include to make these questions answerable can be found in the section "Questions must be specific enough to be answered"
I've been on the internet, and have had a social life on it for the last 20 or so years at least. Nearly every relationship I've had on the internet has been different.
If you want to know "how" to make friends on the internet - I don't think IPS is the right place nor are there any good sites for it. It's a really broad topic. How I would interact with a specific person would be different from how someone else would interact with them, and how I would interact with another person.
If you have a question about a specific interaction it might be, but I feel based off what I know of the site, and the comments - that the answer from Elements in Space is incorrect.
