When I need a new pack of dry erase markers, I spend 45 seconds giving Amazon $5. Two days later, I don't have a dry erase marker problem anymore.
I don't really know how I feel about the future world that's created by universal delivery like this, but there's something wonderful about every "pick up x at store" chore being reduced to a few moments.
I have the opposite attitude, I reflexively down vote grammar nazism and a lack of flexibility for language change. Languages change organically, people spoke differently 100 years ago even and there is nothing wrong with it. It's like razing people for using the word 'like' instead of 'for example', even though they are functionally identical.
Language is a way of associating yourself with a particular group of people. How you communicate determines whether you fit into a group or not. If a comment is just "This" it adds nothing to a discussion. However, the comment above is more valid than your own, because it isn't off-topic ranting.
What you are basically saying is "I use the voting system to attempt to ostracise others because they come from another group". It is never appropriate to dismiss someone who actually has something to say because you don't like their way of saying it.
I don't deny your right to downvote me. Don't deny my right to downvote what I don't like. Please go ahead and downvote my comments if you think they don't add to the discussion (this one is a particularly good candidate for that).
