Personal blogs are back, should niche blogs be next?

> But with the revival of personal blogs well underway

Is it? I haven't seen anyone in my circle return to blogging, nor kids of this generation.

Discoverability is going to be a massive problem, since search engines are dead. Maybe word-of-mouth through social media is enough?

The content will be discovered just fine. It'll get embedded in the LLMs on the next round of training. Won't be attributed to your blog of course, but an approximation to the information will still get out there.
