Why doesn't yahoo answers offer grammar check?

[whatsgoingon?]

It's necessary some of us have learning disabilities or, aren't native English speakers we need a grammar checker because we have trouble doing it manually.

Incorporating that would be even more code to go wrong, like the old spell check. If you have a disability, compose your content on a product that already provides that, like Word, then just copy and paste it here.

Grammar checks never work too well and for many users here where English is not their first language, it would be very problematic. A grammar check would not allow for different forms of English and would flag all text and twitter speak. The biggest problem is that it would be expensive to maintain for Yahoo and they have no money for free services.

Because on there Last Site Not Sure if this is Really the Reason But They Had Spell Check and it Had a lot of Problems With It It Would Tell you you Have Misspelled Words on Words That Were Never Misspelled
