It's not really your decision what's interesting to your readers. You'd be surprised. You've confessed to being a longtime lurker in other places on the internet. You never know what's gonna bring your lurkers out into the open.

Also, do you want to put yourself in the position of blogging to satisfy your audience vs blogging to satisfy yourself? That's asking for burnout. Especially on a personal blog that's not necessarily laser-focused on a specific niche.

That said, I think your readers would probably like to know more about Adria herself and not just blogging/technology-related topics all the time. What have you done around town lately that's fun? Are you going anywhere on vacation (blogging/tech conferences don't count)? What's going on with your upcoming move to San Francisco?

And not everything has to be a well-crafted essay with a beginning/middle/end or a convincing argument or a bulleted list. Just tell us how you feel (although I realize that your brain organizes itself that way).

If you don't have anything to write about, don't bother. You've got traction; people will be there when you do write. If you're struggling to publish for the sake of having published something, it's apparent to the reader. Obviously your situation is different from mine, but you'll notice that I don't blog on swirlspice very often; only when I have Something to Say.

Don't overthink it.
