Sorry for being contrary, but I don't personally like the idea (despite agreeing with you 99.9% of the time ).

First, because I'm not a big fan of any social media platform: this forum is like an oasis in the dessert of the disinformation for me, and I don't think it's right to link it with these platforms. But that's subjective and not a great argument per se.

Second, because I consider it to be an unnecessary attack vector: I receive several scam attempts in Telegram and I have only shared my tag before a few times in bounty spreadsheets in this forum, so apart fro the few groups I take part in, I'm sure that many attempts come from people crawling data from here. If users, specially newbies, shared their twitter/x, instagram, telegram... info in their profiles, they could be very easily targeted.

On the other hand, I definitely agree with you that the ICQ, MSN, ... options add little value and take up space in our summaries. Custom fields would be a good alternative.
