I really liked Greplin (go to https://www.greplin.com/ to understand how it is related to Cue). I vouched for its ability to search twits (and other data source) for such a long time, and now I'll probably have to search for another product, as the team stops focusing on Greplin (and possibly eventually killing it).
Don't mind me though: I'm always happy when a team changes to a product that is more worth their time, even when I liked the former product.
