Popular Internet Abbreviations People Still Actually Use

The quickest way to feel one generation older online is to read a comment thread and realize you know exactly what LOL means, but something like IYKYK or FYP makes you pause for half a second longer than you would like. That half-second is humbling.

Internet abbreviations are supposed to save time, but they also do something else. They signal tone. BRB feels casual. IMO softens an opinion. SMH can sound amused or deeply tired depending on who is typing it. That is why a flat alphabetical list never feels quite enough. Context matters.
