I reckon polio is a good analogy. That illness doesn’t seem so bad at first. Mild symptoms (or no symptoms at all), seems like you get better.

Covid is a bit like that. Most people who get it feel pretty rotten for a few days, and then its apparently over.

I’ve found Mojeek to be a bit hit and miss; but one thing I really appreciate is that they actually do the indexing and searching themselves (whereas pretty much every other search site uses Bing or Google behind the scenes). So although Mojeek may not be ideal, they are at least making an effort to be independent.
