It's primarily about what you want out of it.
The first few times I tried using Twitter to promote my stuff and failed miserably. If you're there purely for promotion you won't get far, and it's definitely not the best channel for that purpose. (Especially if it feels like a slog to you).
If you're there to interact with like-minded people AND share something you're working on in the process, that's a different story. Still takes effort, though.
