Originally, the Suggest tool was almost entirely based on onpage data
Just checking on this. You're talking about the Keywords Suggest Tool itself, not Suggestions provided in the dropdown below the query input box. Right?
No... in talking about the "Suggest" tool, I'm referring to Google Suggest, the search suggestions, which evolved from a Labs project and eventually started offering search suggestions on the main page. It's now incorporated in Instant. (I'm assuming, btw, without having checked carefully, that the search suggestions with Instant on are the same as the search suggestions with Instant off.)
The Keyword Tool is the Google AdWords Tool external. It's available to anyone and seemed therefore to be a proper basis for discussion.
PS - I should probably clarify this...
I should add that on some of the very prominent widgets vs widgets searches, I'm still seeing the plural suggested instead of the singular, but that's on searches where there's a huge bias, onpage and in search, towards the plural.
Here, I'm really talking both about Suggest and the Keyword Tool. Sorry for that degree of confusion.
My comment, "a huge bias, onpage and in search, towards the plural" indicates that common usage is unambiguous. I'm not suggesting cause and effect.
