No need to be insulting. It is proper forum etiquette to do a quick summery of any videos posted for the people who are unable to watch the videos.

When you are going to post a video that is 2 hours long, it is kinda expected. Not only for the people who can't watch the video, but it's a good way to entice others into watching the video in the first place.

You can't just post a 2 hour video and very few details and say "watch this!" You need to also post a quick summery of the video, something that would make us want to watch it.

If you were a salesman, would you just walk up to a customer and say "hey buy this, you will like it!" or would you explain to the customer why they should buy the product, what it could do for them, and tell them about the main features of the product.

You're basically getting sarcastic with someone because they hypothetically would like to know the main features of a product before they buy it. Anyone with half a brain would want to know the main features of a product before they buy it.
