Self proclaimed GitHub star. But still only 5000 followers and projects max out at 8000 stars.
I don’t know what I had expected but I think it was bigger numbers than that.
I've never seen his github account before but I expect that people following him there are doing so because of the content he's putting out. His blog has been on the HN Frontpage many times and has a book about developer career building.
My github account isn't as pimped out as his, but marketing yourself isn't toxic, it's smart.
