CID Skype Name is confusing and unprofessional
The change to for new accounts to use an auto-generated skype id similar to: "cid.5r789ghi979hf79" is a terrible decision.
This name displays when you search for a user and looks unprofessional next to older account names that are readable and memorable. If Skype wish to force people to use e-mail address only then at least hide this string from view and communicate this to users.

Skype CIDs appear to not be recignised by Skype anyway.
