Offtopic, but "mln" really!? I swear I read "70 min new users", which is quite confusing. Is "70 Million" really too long? I can't say I've seen this one before so I'm reeling a bit. I saw "ml" used recently and almost had a heart attack, so perhaps I'm wondering why now?
SI clearly states "M" no? I'd have kept it short and sweet as "70M", just saying. Heh, or perhaps 70 mega-new-users, but I digress.
- The 'mln' abbreviation was probably used to shorten the title so that it would appear complete on search engine results.
- I have also seen "MM" used to shorten "million". I believe that "M" means "Molarity" in SI units, and only means millions when prepended to another SI unit abbreviation.
Without context '70M' should be assumed unitless, and therefor must be interpreted as a power suffix symbol. Better yet, it falls outside the hex range, making life even better for everyone.
Perhaps, if I'm really trying to be difficult, we could try to interpret 'M' as a modifier on 'new users', but that seems silly when there's no space between 70 and M.
>" - I do not understand how 'mln' is more SEO than 'M'"
There are limits to how many characters and pixels Google and Bing will display before cutting off a title and appending an ellipsis. I believe that mln was chosen for stylistic reasons, to differentiate from molarity...
>"[Wikipedia] states that it's 'mol', but what do I know, I'm not a chemist"
'M' is used for molarity (molar concentration), not moles.[1]
