It really feels abrupt, to be honest.

Mostly because most chat messages are single sentences.

So I guess that people leave them out when they aren't part of a full paragraph of text.

Many times I've started writing something I intend to be a single sentence so I'll be lax about capitalization. Then I realize a second sentence is warranted so I go back to fix things and carry on. IM really is an odd medium.
