On the forum profile information page, there are still spaces to write down your contact details for sites like ICQ, AIM, MSN & YIM..
MSN was discontinued 8 years ago now.. Why is it still an option? <...>
Well, we do have this reference to go by, in relation to those fields on the profile:
What similar things do people use now?
Those fields are actually built a bit deeply into SMF for some reason, so it's not completely trivial to change, but it can be done. Low on my to-do list, though, as hugeblack mentioned.
I’ve long thought there should be a spot for PGP fingerprint.
PGP fingerprints are SHA-1, which is insecure. The OpenPGP standard really needs a complete new revision...
So getting rid of those fields is from the profiles is not a trivial thing to do, albeit doable.
Probably adding fields to include currently widely used social media channels would be very welcome by many, specially the youngsters (who may – or may not -repent later ahead linking their Bitcointalk account to these channels).
