Has anyone made a serious attempt yet to codify an etiquette for retweeting praise of yourself?

How strong is 30T relative to say a car junkyard magnet? I have zero intuitions around magnetic fields
Replying to
The strongest magnets you are likely to encounter in natural or everyday settings are 1-2 T. 5-20 T requires special laboratory equipment, and 20-40 requires a special high-field facility.
50-100 can only be created for short (millisecond) pulses.
