Many people replaced Skype with Viber as there's no spam. I have a very old Skype account with a vanity username, which results in tens of Russians adding me and wasting a few minutes a day blocking and reporting them for spam. Also, when abroad, Viber's audio codecs seem to use less bandwidth and provide better audio quality. I actually like the new Skype very much, but the spam issue needs to be solved! There are many fake accounts, no way to merge different Microsoft IDs, etc. I have to agree that Microsoft by not having its full attention on Skype ruined a huge potential! It allowed many messengers to bloom when it was basically a monopoly. Honestly, there's very little that needs to be done to make Skype better and I'm not sure why Microsoft cares less about it!
