As you get more and more specialized, this starts to change. If my expertise is selling matts for large cranes, then there are like 3 companies that do that. The companies themselves are no special, but your expertise in that area does have a special alignment with what that company wants to do.
Non-specialized positions, again, make this question worthless.
I would prefer to use Lemmy, but it simply doesn’t have some things that reddit currently has. It could in the future, but it doesn’t have the user base yet.
