Well I would say games, but then you'd be competing with DSicade.com which already has a good set up.
But neither DSicade.com or DSsdk.com have decent social sections, so there's a gap.
There's also DScomics.com. These are the 3 main sites I'm aware of that are made just for the DS browser.

Adding a facebook like site for just the DSi would be neat (and good on your resume. ;D) and possibly twitter like funtions maybe? lol
I have no idea how complicated site construction is so whatever you do I'm sure it'll be good.

Course I wouldn't mind a simple graphical RPG. lol it could tie into the social aspect of the site..bah too complex.

Also there is a site
http://www.dsibrew.org/wiki/Nintendo_DSi_Browser
That lists some tips and code or whatever to help make the site work better for the DSi if you weren't aware of it already.

I wouldn't be able to wait... but I'm still waiting for my ds lite to break to get a DSi (the hinge on one side is just about to come off) I just can't justify the purchase when i have a perfectly good DS already

cool i'll come when it up

I would like to implement games, but I would like to focus more on the social aspect of DSiHub. Anyway, thanks for the input and your ideas.

P.S: DSiBrew.org's Nintendo DSi Browser page is a good way to start off on a DSi website and yes i was aware of that, that was actually the first page I used to learn the DSi formatting!

Thanks can't wait to see you there!

@SgtSawkz A DSi is a bundle of fun, and when that DS Lite finally does give in do me a favor and buy one, it's one of the best things I've bought! (but then again I am a Nintendo fan boy...)

I like DSiCade, but this might be cool, too.

@lunchmeats101 I can assure you it will be...!

I'll totally join...

I'll join, too... weird that webpages are more fun if you visit them with the DSi

Can't Wait

All I can say is... THANK YOU!

I did much of the authoring of the DSiBrew page so that people making a DSi website would have a good base to start from. Instead, most people have chosen to rip code from DSiCade, thus confusing users who think the new site is related to DSiCade. (My off-the-cuff disclaimer seems extremely popular. )

Soooo.... THANK YOU for making the effort to work from the information published for that purpose!

wow dsi games on a web site playable on dsi browser that is hard to belive. you should make like some free app on the dsi shop for your web site if it does well. you should make alot of DLC for the dsi as well -if the browser ever gets updated to be able to download things straight of the dsi browser

A private messenger system that can talk with other systems like AOL and MSN would be brilliant. And uploading of DSi photos is a must. Looking forward to this site already.

nevermind not hard to belive any more - just saw dsicade -

Well I must thank you for that page it has certainly helped a lot!

As far as picture uploading goes the browser as far as we know it isn't possible but if it was this would definately be something to look into to....

This sounds good to me and I've been following this thread. I love using my DSi to access the internet, even though it does run a bit slow. So having some place to 'hang' out as you say would be great. I look forward to giving your Hub a try.

Bubby... I love your name on here. Most my friends call me Bub or Bubby. LOL. I think the alternate website is a good idea. Thanks for the DSI goodness!

@ballistickboy Lol, my bro actually gave me the idea for the username and I've used it ever since! Thanks for the input, I think I'm going to go through with the alternate site but I want to finish up on the DSi site first since this is my main focus.
