I've wondered a few times if it's worth continuing my blog. I don't have a ton of readers; it doesn't really earn money; it's hard to tell if it helps my writing goals (as a writing portfolio, getting hired, etc); and blogging's old fashioned (everything's now about video/podcasts).
Also not sure if what I write about is interesting or useful enough for others. Reflection of my (esoteric) tastes, etc I suppose? Even with splitting off the tech and media posts as semi-separate blogs.
