How would you filter everything out? That's a lot of white noise to process efficiently and quickly. Can't see it being a great deal of help during a social/business situation... unless you're going to pause awkwardly for 5 mins while you sort through all the suggestions. Same thing for extending the senses.
You could use something like reddit to do the filtering.
You probably don't need to pause for five minutes because most social/business situations last quite a bit longer than that. You could probably say something later.
