I dont know, but it'll be awesome.

Is it a jet pack...I quite like that suggestion? Or a banjo that doubles as an ipad?

what else... HTML5 for Web3.0!

I know - you're working on collecting ideas from all these tweets until you see one you feel like implementing ;-)

A Rumor-trace search which gets to the bottom of the age old problem: "Is that really true?" by finding the first mention thereof. This will give credit where it is due, and root out lies. Not only that, but this will automatically pin blame upon said user.

You're figuring out a way to turn ideas into actual money.

@untitledstartup is building Facebook meets Twitter... or the version of Facebook Zuckerburg launched when he failed to buy Twitter.

i love how there were multiple jet pack guesses. im going to have to stick with the masses: jet pack. oh wait...you already told us? start redesigning. that was a fast fail.

i'm going to guess it's a seat filling algorithm for large venues...

I think you're working on training cats to climb ladders.

You're not actually building anything, it's going to be an online web series about two dudes building a startup (even though they're not). How meta...

Weaponized IE 8 0-day ^_^

backing up all sorts of tweets in google spreadsheets ... ie. google docs spam machine?

Looks like a startup reality show...

Crushing Facebook, kicking web 2.0's ass, fueling AI with human power, capturing every tweet and turning it into energy again...After much thought I have resolved that you are creating a social media service that uses a persons location to deliver content or connections they might be interested in based on their preferences and habits. Ex: If I drink coffee daily at Fremont Coffee Co. in the Fremont neighborhood and then visit the Wallingford neighborhood for the first time then you will tell me about coffee shops that I might enjoy based on my social media habits + my geographic behavior + frequency...the app is intelligent and doesn't bother me with the same suggestions upon repeat visits to Wallingford. It doesn't end there. It extends to my reading habits, my purchasing habits and even my hygiene. The app is a service any business on or offline can bolt on to their marketing and social media strategy. In short you are "untitled" because the app is god-like and knows when, where, and how to deliver every answer the universe has to offer....so how could you even title such a thing :) You have my full attention.

You are working on building an open community . thats all that i can say for sure !

SMB CRM that doesn't suck.

It is a hypnosis service administered through twitter. You got me. Damn it!

Using Twitter to somehow help the Seahawks with their run defense

working on focusing on executing...something.

I don't know what you are working on, but have an idea for one that would revolutionalize an industry that desperately needs it!

you're building video twitter (kind of what Seesmic was before it became a Twitter client)?

oh yes! build a jet-pack!

A name and idea generator for startups.

@UntitledStartup is working on a Crowd-sourcing application using social media tools. Or a jet-pack. I hope its a jet-pack.

embeddable chatroom like disqus (not flash) and sign in via Facebook Connect.

Are you inventing a new kind of chocolate? That space could handle some innovation.

Unbridled awesomeness

twitter and blog search = crowdsourcing feedback engine

a combination of chemical reactions in order to get the desired product

Are you guys saving us from End of Days 2012? Someone's gotta do it!

It's too bad computer monitors don't radiate much UV, you pale bastards. Wait that's my idea

Bringing the world cheek to cheek

i don't know but whatever it is i sure hope we can list it on www.oneforty.com!!!

a cure for the common job. or a metal band. either way it sounds cool.

An alternative to the "y" chromosome

taking over the world?

no idea!

Nathan Kaiser Baby Name Generator?

I'm almost certain that you're making an app which scans cocktail napkin drawings of robots and then 3D prints them.

hopefully not Skynet.

You're crowdsourcing ideas for what to work on!

Guessing it's not a new word processor for windows -- http://bit.ly/8ktdHW

Wait, it's an "open startup" but you won't tell us what it is about? I want to support you guys, but how is this not "stealth mode?"

a sparkling unicorn rainbow fairy dust generator written entirely in PERL?

I'd tell you, but then I'd have to… Well, you know how that ends :)

It better not be a fan club site!

I think you are collecting a bunch of ideas from people trying to guess what you are working on, then you will pick the best of these and do it.

the startup is this site! they'll be white-labeling this type of site for folks who want to create their own online tv show. man, that's a weak guess if i could say so.

I think you are building a crowd-sourced startup to build crowd-sourced startups.

some sort of content gen. app based on twitter or other user-contributed data..... i.e. taking those stupid twitter lists + pulling out trends or sub-groups?

A *very* clever way to help monetize Twitter that will also eliminate the 140 char limit per tweet. just sayin' =)

Knowing Damon it's something statistic related

A Twitter app that spawns yet other Twitter apps?

it involves rocking buffet tables and record labels.

if its anything we've ever discussed, i am contacting my lawyer ;-)

I think you're working on a REAL HINT for the next video :)

I think you finally got the ability to stab someone over the internet working!

The ability to finally stab someone over the internet!

Some tie in between Twitter and porn. Definitely porn.

Well I sincerely hope you guys are working on ways to make my life in communications easier!
