This! People read devlogs, and they also get indexed in search engines very well. They're also the only way to make your game count as new again once you do release something (by marking the devlog as Major Release). Otherwise, while you don't have anything to download the game won't even appear in searches. But it's fine to have a game page simply for the presence, and many people do that.

Sounds great! I like doing devlogs... that's what I mean when I say I want community feedback and keeping myself accountable. I published this new project today, Mars Tower Defense just so I could have the devlog.
What am I missing tho? Am I supposed to (and how) create a "bare" devlog without it being part of a new project? Do I keep the project private but publish the devlog inside it?
Ah, if you don't want to make a project page until you're ready, just start a topic right here in the devlog category. Those are sought after too.
