@JMMaok Nah, I'd rather keep my social life and personal opinions detached from my job.
Twitter burned the mind of a lot of people by convincing them this is a nice practice.
Do you want to share stuff about your job with your peers? Well, write a blog: that's how I follow scients that interest me and that's a way through which they actually give some useful insights about their work to others.
If you're just going to say you published a new article or participating to a conference, that's not really useful: if I'm interested I'm already receiving mails about the articles you publish.
