I'm new to blogging (shameless plug https://raskie.com), so keenly feel the pain of writing content. But it's a satisfying experience, even if it can be a bit frustrating. If it's a tech blog, sometimes, the feeling of completion is at least as satisfying as solving a particularly difficult programming problem, or writing a small program. All the more satisfyingly when people read the content, and appreciate it in some small way.

So yeah. I find it valuable, even if I do sometimes feel like 'I could be writing some code / designing something right now'.

A problem I think I have is knowing when to stop writing... I look around at other people's blogs, and see all these succinct, perfectly targeted paragraphs, all the while considering my work to be bloated and overly long. But I do try to reread and rewrite stuff. I think it's a skill worth working on, so that's another reason why I spend the time doing it.
