The biggest problem is that many users don't know the correct markdown syntax to create an inline link. This can be annoying if you want to add a long link in a comment.

Also you cannot post insanely long links like this.

The biggest problem is that many users don't know the correct markdown syntax to create an inline link. This can be annoying if you want to add a long link in a comment.

Also you cannot post insanely long links like this in the comments or in chat. If all shorteners are banned, how can I post my really long links?
