Nice post. Thanks for mentioning Intercom (https://www.intercom.io/). I don't think people generally find the social profile stuff creepy, but I'll admit that knowing who they are on Vimeo, etc. is not very useful. We just link-up whatever profiles we have but don't give them much priority in the product.
streak are nice but a little rough around the edges. sometimes I wish they did work over a real google spreadsheet that you could access separately.
the most annoying thing is how they link emails to 'boxes' (btw, wtf is it called a box? ;). if another user adds an email to the box it sometimes doesn't show it in your emails (although you might be CCed on it too) but instead delivers it from what is stored on their servers and it looks garbled. all formatting is lost etc.
I'd prefer them just adding a label per 'box', so that adding an email to a box would be as simple as adding regular gmail label. and that would discover it and replicate among all users.
