The worst search engine except for all the others. Compare to Bing and be SO grateful Google got dominant first.

I tried for years to help build this site into one that was usable by normal human beings. I used to think this site, with its incredible assets in groups and topics,
Would go beyond the bulletin-board quality of the Newsfeed. My reward for this has been to get banned for life--my offense was attempting to get them to fix a glitch that was chasing away Users left and right. It came at just about the perfect time--thanks to Mr. Musk's Twitter wars, I realize that most of their "members" and "viewers" are robots spying on your posts and doing their best to steal your information.
Confirmed this to my own satisfaction by posting to several of their "Groups" with any number of tidbits that should have provoked extensive chatter. Nada. There seem to be no people on any group except for a very few regular contributors.
ND gives you Post Insights which suggest you have tens of thousands of people seeing your post to their Newsfeed. What you have is a few people checking in again and again plus the aforementioned robots looking at it THOUSANDS of times.
My regret with this site, which now seems to have extremely sparsely utilized neighborhoods, is that when it inevitably goes dark there is no competition save in a few select neighborhoods--naturally those are the very ones that least need such a service for their disenfranchised and their shut-ins.
Experience in two different 'hoods tell me otherwise. Also, from the comments
In ND reviews, neighborhoods become defacto right or left, and exorcise any in-betweeners.
So it's not really a fit place to discuss anything BUT your lost or found pet. "Moderators" in
Some cases are overly zealous, in others, absent in the face of any controversy.
As for use in emergencies, if there's a 3.0 earthquake(I write from California), you get twenty posts that ask, Did You Feel That? Of course these quakes are almost always too small to be WORTH talking about anywhere.
In short, ND offers nothing to see here, At least nothing of value.
(This is a replacement of earlier, more positive reviews which I now regret.)

Almost never took me where I wanted to go. I've used it only for sites it's gotten me to in the past (chiefly Google) and even then I've been experiencing frequent computer freezes. Coincidence? Maybe, but I try to remember not to take the easy route these days.

Try it for whatever interests you the most in life, in the world of Things. Cars, artwork. Best feature is quick save of most things you see on the internet so you have instant photofile.
My SOLE complaint, they do send you suggested pins you might like every day, but I often find something there that I DO like. I find it invaluable, and have only some thousand images on my "boards" so far. A really deep-end artist could spend days seeking and finding inspiration. And, no, i do not own stock, am not an employee or agent--just use it and LIKE it.
