Same here. Dropbox is the best YC-backed product to date, IMO.

Ahem, TicketStumbler.

Just kidding, I'm in love with their service and am a very happy user. They're backed by Sequoia and some other BSDs.

How the hell do you make something boring like file storage viral and cool? I don't know but Dropbox just did it.

How is it viral?

Not only have I enjoyed it so much I've told countless friends about dropbox, it also auto invites your friends to join when you share a file with them. That's in part why they already had over 100,000 beta testers before even launching.

And rejected from YC the first time, if I remember correctly.

Agreed. It's the second one (after reddit) I will actually use, and the first I would pay for - anyone know what pricing will be for going beyond 2GB?

Answering my own question: $10/mo for 50GB. Not bad.

Your comment really reminds me of this:

"...What you want to be able to say about technology is: it just works. How often do you say that now?" -- http://www.paulgraham.com/ideas.html

A damn good sign for Dropbox methinks.

What makes something a winner is often very small. What makes that essay a winner is this:

You can't just say "Err" to the user of a stove.

I love Dropbox, but I've also used Foldershare across all my PCs (and friend's PCs) for years now and it's been great.

I prefer Dropbox now (it's superior), but I never felt like this wasn't something I didn't have access to beforehand.

What do you mean "of its kind"? Windows Offline Files and briefcases actually work. Volume Shadow Copy actually works. WebFolders actually work.

They're just not as well connected or cross platform.

Rsync works too. But I'm not going to ask my Dad to install it.

I've been using Syncplicity, which offers similar functionality, and that works too. Clearly, their PR isn't as good - it's been launched for some time.
