Weird question, perhaps...

I am often too nice and simply give an upvote to almost anyone who chimes in with a Reddit recommendation, whether their favorite sandwich shop, pizza parlor, day trip, favorite barber, etc.

It doesn't even mean I've been to these places.

It's just that I'm appreciative when someone simply responds with certain answers, especially if I haven't been aware of the place or of its particular recommended -- or even disparaged -- items described.

Is it more valid for upvote and downvote results in any Reddit sub to only give upvotes or downvotes to places and products I am acquainted with...or also okay to give upvotes and downvotes to places and things I haven't even tried -- but simply appreciate the info in the post?
