WHY IS +1 WRITTEN ON A COMMENT OR POST?

-2

NOW YOUR TOPIC IS DEAD!

Thnx for skyrim +1

x1

because people love Google+

because.... why not!? >:D

+1 means that they agree with the person they replyed to

It's like Skyrim but +1

Because there is no downvote system like on reddit, so people can post anything, even if that what they post adds nothing to discussion.

cause never +0 , hhe

It's the same reason as there is no "Double Like" button on Youtube or Facebook. One people, one vote.

When someone replies "+1", it usually either means:

The user agrees with the post he is replying to.
The user 'likes' the post he is replying to.

"+1" can be considered as a "thumbs up" or "like". It is often used on forums where a "like" or "thumbs up" button is nonexistent.
The reason it is "+1" and not "+2" is because it means that there's "plus one user that likes the post".

Sometimes you will also notice that some users will just reply "+" instead of "+1".

why so much shouting

It's our special way of upboating posts when there's no actual upboat button.
