I work 100% online, but I hate reading post and commenting or even liking on all social medias, specially on LinkedIn because I don't care 100%, but it's a big mistake nowadays as I need to build connections and give visibility to my profile in order to sell my services.
I wanted to give PowerIn a try, and it's really amazing, the comments are pro, and started getting visitors + invitations since day 1, it's a great tool, I recommend for shy people or those who hates being on social media like me. I will upgrade to a higher tier.
