Having an online presence has not significantly helped me out other than just to build my own confidence. Each year I get a number of blog posts on the front of HN and a couple of technical tweets that get modest attention (100+ likes) and it's never really been a source of jobs or promotion. Recruiters and even most hiring managers are not watching these spaces and not capable of evaluating the merits of blog posts or projects. So it's time wasted if your only hope is to attract recruiters or managers. I learn a lot though and I get practice writing. I think that's worthwhile personally.
