Yeah, I don't get a lot from the majority of posts, I just try to at least curate the lower quality stuff out. I don't mind posts on releases as long as they aren't like every week (multiple times a month).
I posted on the Node update a few weeks ago as I thought SQLite in the box was particularly noteworthy.
I could honestly do without most of the AI posts, and definitely the blockchain. When it's an obvious service ad, I tend to delete, unless the post itself has value beyond that.
In general, blog posts seem to be a lot of hit and miss. I'd also like to see a bit more discussion on the site, I know it's kind of hard and most are using it as a casual reader aggregate. I do too.
Going to try to cross-post anything interesting from HN and some of the mailing lists I'm on. I don't always keep up with it well, but would like to see things grow. There's definitely room and definitely plenty of new content that can bring that out.
