@aral @letsencrypt So pretend you're looking for a plumber and you happen to drive by a plumber's truck in your neighborhood. They have their web site listed on the side of their truck.
Would you rather have remember mycityplumber.com or 135.181.044.050?

Plus, no more shared hosting.
Along with the problems others have mentioned.
There's a reason domain names were invented in the first place.
