I've been a Dropbox user for--I don't know how long. A long time. I would say since...maybe 2009?
I do not know what those products are for sure. By their names I'm guessing something with photos and something with email. I feel like an old evangelist like myself would have known more about those products. Thus, I wonder if this was a marketing failure as much as a product-market-fit failure.
Likewise, I've had Dropbox since around 2009 or 2010, never even heard of Mailbox until now. I actively avoided Carousel solely because of how much the mobile Dropbox app was trying to push it on me, my reaction was more-or-less "What? I'm not changing my workflow." and ignored it. Might have been a shame, but it didn't feel welcoming with how they tried to do that...
A while back Dropbox said that they had grander ambitions that being a single-product (Dropbox the service) company, rather they wanted to be a sort of Microsoft, Lotus or Borland of the current generation.
This statement preceded the acquisition of Carousel (a sort of alternative to iPhoto and Picasa built on Dropbox [the service]) Mailbox (an alternative email client, no technical connection to Dropbox [the service]).
So yeah maybe this strategy isn’t panning out? I dunno, just irritated that the default move for abandonware isn’t open-sourcing it.
