To The Future! A List of Intention Enabled Websites

In my opinion, you've left off the biggest of all -- Goog. After all, 90% of Google's revenue comes for harvesting 'purchase intent' -- majority of the ones listed above converge on the intent of events / places.

'Intent' can be relevant to just about anything -- intent to buy, intent to eat, intent to visit etc..

Socializr seems to be gaining traction, and is a much nicer alternative to Evite. It lets you add external accounts to include events from Facebook, MySpace, Upcoming, and Evite.

A few music industry related intention based sites I'm aware of that were around as early as 2006:
www.eventful.com - fulfills the intent of the fan and the artist.
www.ilike.com - again, let's artists know how many fans want to see them in their city and notifies fans when an artist lists a tour near them.

The future as I see it - a mix of intention based, location based and augmented reality paired with RFID and micropayments (NFC, Square):

I link my wish list to my geo-targeted shopping application. I'm driving and my phone vibrates, tells me I am passing a store that has items on my wish list. Also displays stores within 10 miles and what the prices are there. I walk into the store and my phone presents me with a QR code my friend sent to my phone that they got from a print ad, tv commercial or sign for a list of instant rebates on the items I have listed in my wish list that we both share. I walk up to the box, scan the QR code with my phone and it brings up a product tour, all the ratings and reviews on that product with ratings, reviews, wish list items and products purchased by my friends and family. I hold my camera up to the product and application/benefits type images are overlaid on top of what I am looking at. My phone asks would you like to purchase? I decide to purchase using my Sqaure - payment enabled phone. The RFID on the box is then deactivated and I am free to put the box in my cart and walk out of the store without ever seeing a cashier. I then have the option to broadcast my purchase and share the mobile QR code instant rebate with my friends. My wish list check off my purchase and sends me a timely reminder to leave a review as well as suggest related items I may be interested in including items my friends bought - kinda like Amazon I can see apps like twitter360 partnering with ilike, eventful or live nation to take the intent idea a step further. Now fans can connect with other fans (like fellow friends and street team members) at an event. How about when you go food shopping? Again, a shopping list is created, you get to the store and that little sign on the front inside of the cart? It's now a screen with a map that guides you through the store via GPS to the items you need in the fastest route possible. Tie coupons to that - no more shelf talker printers in an asile printing coupons. A QR code is sent to your mobile device to scan at the register.

Anyway - very interesting times - end ramble!

How about Change Everything, an online community of changemakers in the BC area (http://www.changeeverything.ca). The site is "fun, it's free and it's a great way to work towards positive change for you and our community."

don't avoid social bookmarking at all, it can give you a visitor instant, do posting as you can in these type of sites..like http://digg.com, http://tweetme.com, http://ja-ta.com

Dopplr.com of course.
Also, check out your carbon footprint according to your travel.
+ It uses behavioral data (Amazon style) to provide traveling recommendations...

Jeremiah, www.mixin.com fits your criteria completely. The current version has limited functionalities, but you can already check it out (also available on your iPhone, same url). The upcoming version will be really great, including full integration with facebook (fb events, creation of events on fb, social graph, fb application) in addition to twitter quick post, gCal synchro, dopplr and more services. This version will also provide more widgets to not only aggregate your social peripheral vision but also share your upcoming micro-agenda. Don't hesitate to contact me if you want more information.

As much as it pains me to say it b/c it is one of the least innovative sites out there, Evite seems to fit the bill of intention enabled websites.

Couchsurfing www.couchsurfing.org is a full of people broadcasting travel intent, updates, connection, and planning social interaction and communication :-)

Thanks Jasmin, added, and credited you.

There's also localist.com, which is set up in several cities and offers a branded platform.

Great post, Jeremiah. Since an election cycle is fast approaching, how about including prediction markets like http://www.fivethirtyeight.com/

Foursquare, Gowalla, Loopt, Brightkite and other check-in based apps should consider adding: "I'm going to be at..." features.

I took a look Andrew, Im' not sure it fits my criteria.

Hi Jeremiah, All these sites are social directly, I don't know whether it would be relevant to mention or not but in.com and some others boast a future email option in which you can write an email and set a time in the future for it to leave the outbox.

Thanks Akash, I'm not sure, but does it fit the criteria? Having a hard time finding out if it really puts 'intention features' front and center.

I think so as email is again form of a message which we usually send intentionally to others but in this kind of a service we know what would be the right time for the other person to read it and I think thats what intentional web is all about, Plus I must says you can get your thoughts on this a lot better then me.

Triplt as well

Thanks, I added it, gave you credit.
