Capitalization and Punctuation

Capitalization is a non-concern when using text message abbreviations and chat jargon. Whether you use uppercase (e.g., "ROFL") or lower (e.g., "rofl"), the meaning is identical. Avoid typing entire sentences in upper case, though; that's shouting in online-speak.

Punctuation is similarly unimportant with most text message abbreviations. For example, the abbreviation for "Too Long, Didn't Read" can be abbreviated as "TL;DR" or "TLDR." Both are acceptable, with or without punctuation.

The exception: Never use periods (dots) between your jargon letters. It would defeat the purpose of speeding up thumb typing. For example, "ROFL" should never be typed as "R.O.F.L." and "TTYL" should never appear as "T.T.Y.L."  

Etiquette for Web and Texting Jargon 

Know who your audience is and whether the context is informal or professional, and then use good judgment. If you know the people well, and it is a personal and informal communication, then abbreviation jargon is perfectly acceptable. On the flip side, if you are just starting a friendship or professional relationship with the other person, avoiding abbreviations is a good idea until you have developed a rapport.

If the messaging is in a professional context with a coworker, customer or vendor, avoid abbreviations altogether. Using full words shows professionalism and courtesy. Err on the side of professionalism and then relax your communications over time.
