I absolutely love the clearbit integration on record creation. So much so that we should really, really add it to existing contacts.
i.e. its great that creating a new record gets all that data filled in, including social links.
but, if i am a telemarketer using existing data in my database (like we do) then i would love to be able to load a contact on my calling list, click an "social search" or "social research" (or similarly named button) and have it perform a clearbit search using the users email address (or indeed using all the email addresses given) ... and then popping up a screen to tell me where there are differences between the data we have and the clearbit data. Obviously we dont want to immediately overwrite existing data, but we could offer updates where the existing data is missing or in conflict, and we could certainly recommend adding links to LinkedIn, company website etc.
