I've been getting the odd invitation to join ResearchGate ever since my journal article* was published.
My paper is not going to set the world on fire, but more than 5 years after publication, I'm still getting a few pageviews a month and the odd citation. As I mentioned here, the paper hasn't had much of an impact on my post-graduate career, other than the fact that it looks nice on a résumé.
I have no intention of going back to grad school. I also don't have any future papers planned - I do present at the odd conference, but I'm not in a place where I'm advancing the science to the extent that I could get a paper out of it. And my existing paper is already open-access. So would joining an academic network really do much for me or for the general public?
I'm already a piss-poor correspondent and facebook/linkedin updater. I'm not all that interested in committing to yet another social media outlet when I barely use the two that everyone else seems to be on. But maybe I'm just an unsocial crank. Readers, do you use ResearchGate at all, and do you find it useful compared to other networking sites like linkedin?
* as with most academic papers, it wasn't mine alone - I was first/corresponding author, but it was a group effort.
