You can only participate proactively and effectively in a small number of social networks, two or three at best. At least that’s my personal opinion. You can, of course, set up a virtual presence anywhere and everywhere. But should you? That’s a different question entirely. We could probably argue all day about the relative value of the time it takes to set up a profile if you’re not going to connect with anyone in that specific network.
Disclaimer: I sign up for social networks I know I will never ever use, just so I can see for myself how they’ve crafted their user experience and take a closer peak at their unique selling proposition. So my presence on any social network is not an endorsement in and of itself.
