There was a site that was integrated to the app itself called "Flipnote Hatena" where you could look at the works of others.

It was pretty ungoverned, very un-Nintendo in a way, and it was nifty. I think it's back in this version.

OH MAN!! I AM SO EXCITED FOR THIS! I loooooved Flipnote.

Edit - Club Nintendo is down. Figures.

I got my code, but eShop says the distribution hasn't started yet. I want to draw and share stuff again!

Have any of you downloaded it yet?

It's not down for me.. but whenever I get to the page to select it, it's blank.

I was able to sign in, but when I chose it, I got the "Club Nintendo is Down" page again.
Noooooooooo!

I've downloaded my copy. Take that slowpokes!

But I'm at work so I can't play it yet.

@HammerLord

I'm downloading it right now. It took a sec to log in but then I did and now it's let me earn my code. I put it in the eShop and....

now it's actually downloaded and open on my machine. Try again if you didn't just do it recently.

Ah, dang it. I checked the error code in Nintendo's techforums and I can't redeem it because my eShop and NNID's region are Brazil. This promotion is happening only for Canada and the U.S (the only eligible countries for anything in this system), so it's impossible for me to get the app. I used to have ways around that, but now I can't just change my account's location, since it will compromise all the games I bought. This is upsetting.

I guess I'll wait and see if they'll bring this to the rest of the world, by allowing people to download it straight from the shop.

As far as I know, you can't share drawings online... only locally. Yes, locally. Where you could just show it to the person instead. I suppose they could save it to their system but whatever. No bouncing penises for you!

@VofEscaflowne
ARGH, you're right.
Hatena has been taken from the app. What a loss.

Well, my hype for this has crashed.

Maybe they'll add it?

@DrFinkelstein
Apparently the Japanese one has it, but to me it seems like NOA is pulling a "Swapnote" on it, and not allowing sharing.
Drives me mad, I tells ya.

@ploot

Hopefully Reggie will speak on it's behalf at some point. I wish the gaming media would do a better job hunting down answers to this stuff.

Per website:

Flipnote Hatena has ended its service.

We would like express our sincere gratitude to the members of the Flipnote Hatena community which began in December 2008. The service has now ended, but the memories will always remain.
Thank you all for the amazing flipnotes and for your use of the Flipnote Hatena website and Flipnote Hatena.

Thats ok people, no biggie cause, the memories will always remain. What a joke! We have no memories of nothing. Why even give us something like this, when one of the main features of the software isn't even available anymore. I guess I'll just stare at my own creations all day and make my own...

Memories, pressed between the pages of my mind,
Memories, no more sweet hatena, might as well just drink this wine

You can export a gif or avi of your 3D flipnote.

Gifs aren't 3D but you can use them anywhere.
Avis can be viewed in 3D in the 3DS Camera. You can also upload them to Youtube to share them (presumably 3D is an option there too?).

I am constantly reminded that I absolutely have no talent for programs like this.

@Infinitywave

I hope you and others post your wonderful creations.

@chrisbg99

Ditto.

I've almost got it! Club Nintendo is struggling to bring up the page that gives me the code. Almost there....!

I was able to download it last night...small file (64 blocks). I'll play with it some later.

Thanks DrFink. I don't know when this hits the UK yet.

Hmm, there's a mode that supposedly allows you to import your DSi flipnotes and search for other users DSi flipnotes, but since the service ended, I've got to imagine you can't actually do it.
