I spend 8+ hours a day working with/ingesting data. Had no clue. Checked with my data-using colleagues just to see if any of them had heard of Arrow - about 50% had. These are people who spend their entire day working/ingesting data in various pipelines. So, while I won't comment on whether the subtitle would be useful, I'm pretty confident that the (perhaps not large) majority of people who would/could use Apache Arrow had not hear of it. A lot of people just stay in their lane. Having a solid description, like the one you provided, would be super useful. Perhaps a tool-tip feature of HN, even.
