Communication/Talking

Offlate, i have been coming across people who yap a lot.
Go to office...yap....go to market...yap...getinto a bus ...yap
Is yapping a God Gift,or a talent imbibed is what i have been thinking? By the way, can yapping be termed as a talent?And people good at talking, build buildings,just with their words and try and get away either by hook or crook. And the innocents are held for no mistake of theirs, just because they are not good at talking.
I have been a victim myself of people with long tongue.Have been ripped right and left. But am learning to confront the situation.
Can the readers tell me how to improve on the talking skills?
