I currently have the following pieces of software running on either my phone, desktop or both :
- Jabber client
I believe that it is much more than what I ran a couples of years back with AIM/Yahoo/MSN gone , I thought the messaging scene would unify. (And I'm not running whatsapp/instagram/....). I wonder why people don't stick to open standards - well I kind know the answer, you use the tool the other one uses to be able to communicate with it. Too bad things like signal don't get more usage.
