"Login" is not a verb

Blindly accepting all changes goes too far in the other direction. People can write however they like, but people with an interest in communicating clearly in written English usually adopt a middle way by developing their own style based on a mixture of conventions they've been exposed to. For example, I typically write in semi-formal US English influenced heavily by the Chicago Manual of Style.

There's a beauty in having standards in order to make certain categories of text (such as work e-mails, quotes, or newspaper articles) easier to read and understand, but there's also a beauty in having multiple standards that are flexible and can slowly adapt to changing tastes over time. No-one is fixed in how they have to do things.

I don't believe we should encourage people with an interest in communicating clearly in written English to simply "do what they're going to do" but to appreciate the gamut of professional written English and to try and stretch the boundaries of it little by little, without falling into heavy use of slang or neologisms. Written English is a different beast to everyday, casual speech.

The English language moves, for sure. I believe, however, the vaguely defined standards of formal English shouldn't be ignored, changed too rapidly, or pushed in too many directions at once. It takes people time to keep up and, at the end of the day, clear communication is what it's all about.

Even more remarkable is that native speakers use these constructions all of the time, yet the idea of a phrasal verb is apparently not taught in school.
