Cmv: i think reposts are a good thing:
I understand there is a lot of disdain towards people who post a question or an image that has been posted before, however I personally think it's a good thing that people do that.

It's true that the person posting the question could easily do a search of previous posts and get their questions answered. However that deprives all the viewers of seeing an answer if they never thought of that question in the first place.

Let me give you an example, I'm a huge fan of /r/askhistorians however I've never asked a question on there. I rely on others thinking of interesting questions I wouldn't have thought about and then reading the answers to them. 

It works much the same with many other subs. 

As there's no easy to way to view historic posts unless they are "top", unless things are reposted then there's no way for others who didn't see it the first time to see it again.
