Both work depending on your audience and how they’re finding you.
In my view, less often but longer is preferable and there are some others who would agree with that viewpoint. This post goes into quite a bit of analysis and a YouTube report I read recently was pointing in the direction of longer videos so it’s not just written content.
That said, if it’s the difference between putting up short-ish posts or none at all because long-ish ones seem daunting then go for the shorter ones. My recent posts seem to be in the 1,000 word region and I can type those quite fast. As a reader, if the info is interesting I’ll keep reading, if it isn’t then it doesn’t matter if it’s only a few hundred words.
