People who write online, be it blogs, comments on articles or other Internet writing. The style of writing is at once witty and informed. Clattering on the keyboard irreverently, yet still having a literati message of import. The word is a portmanteau of "clatter" and "literati".

A subset of storm watchers, these are people who derive enjoyment from watching and being in storms that involve hail. The "clatter" is the sound of the hail hitting roofs and other metal or wooden objects.
