That being said, their results are not the best. I would probably recommend MetaGer.
I know Mojeek have their own database of pages that are not taken from Google or Bing or anywhere else.
Partially. But most people, myself included, use it to track the ratio and statistics of their studying. For example, I like to check the stats page to ensure I’m not spending too much time studying one thing and not enough time studying another. Additionally, I like to make sure I’m studying a consistent amount from one month/week/year to another so I can ensure I’m not dropping off.
Also, I feel like it’s something people probably don’t wanna talk about, but a lot of Reddit’s appeal is in NSFW content - so a NSFW instance would also likely increase users.
