Academic social networks can provide some opportunities for meeting others in your field and promoting your work, but please note that they will track your personal data and email you incessantly in exchange.
Can you share it? One important aspect of using a platform like ResearchGate or Academia.edu to post your research is whether you're actually legally allowed to do so. Check your publisher's policies prior to posting with the Sherpa Romeo tool.
As the social media environment evolves, many researchers have moved to LinkedIn or are increasing their usage of the platform beyond posting their CV to more actively post news and updates about their research.
Consider your personal policies when deciding to use LinkedIn for this purpose:
Academics have established spaces in general-interest message board platforms to discuss subjects of interest to those conducting academic research and working in higher education. These discussions allow researchers to check in with their peers for advice, feedback and potential collaboration.
While these platforms are generally available without an account, certain functions are only open to registered users. Before creating an account, be sure to read the privacy policies so you know what the websites will do with your user data.
