The single best thing I ever did for my career was start a blog on my own website.

Writing on your own website associates your thoughts and ideas with you as a person. Having a distinct website design helps strengthen that association. Writing for another publication you get a little circular avatar at the beginning of the post and a brief bio at the end of the post, and that’s about it. People will remember the publication, but probably not your name.
Another great reason for Why to IndieWeb.
