This is my #1 tip if you plan to publish anything online, as text, images, audio, video, or any combination of content ...

#1 publish only content that interests you.

I've noticed that If I try to write about companies, or try to write stories that don't interest me, it becomes very difficult, and the content doesn't "look" right. Writing about things that interest me, makes it easier to interest others, in the things that interest me. That's my advice but if already blog, or self-publish in any way, you most probably already have noticed this interesting quirk of online publishing.
