What product you have heard of can greatly depend on your responsibilities within the company. If you're focused on product, you will almost undoubtedly have heard of Balsamiq. On the other hand, Dropbox is increasingly being used across the organization (sales, engineers, etc).

I didn't know that it was called "Bingo Card Creator", but I immediately thought "oh, that must be Patrick's startup" -- so I think that qualifies for "brand awareness" even if I didn't know what the brand was called.

I predict you will see a bias toward companies at the beginning of the list, as people see how many there are and give up. I did. If I were you I'd delete this and repost with a list of 5-7 cos.

Will do.

I think Dropbox is the only company on that list that I know for certain I would have heard of without HN.
