Network effects. I&#x27;ve been forced to install the client (Linux) twice for work. Worked fine for calls&#x2F;chat, but I&#x27;m not keen on running it, to say the least.<p>Also, there are project managers in my industry who check availability of freelancers via Skype, rather than email. Remaining logged in keeps you visible with them. I don&#x27;t do it, and I find it a shame that this is the state of affairs.
