> 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?

I have been blogging for decades, personal and work. I look at traffic patterns and see all the comments coming through.

I don't think personal blogs are back.

Niche forums. Federated.

Don't call it a comeback. We've been here for years.

Two years ago I started a niche blog and tech site focused on hardware and software guides for Linux creatives. Even set up a forum because I was fed up with digging through scattered mailing lists, and Discord servers for information. I like to think it has helped some people and it gives me a chance to practice writing human-readable documentation.

I was wondering what the definition of "niche" was going to be:

   Kottke is one of the better known blogs that does not have a specific speciality. 

I think that's a good one to highlight as NOT niche, and niche is much more specific. Like I've had a librarian blog since 1999. Pretty much niche.
