Crowd Science Demographics is a new audience measurement service that gives website publishers insight into the demographics and attitudes of their audience. Focusing on more than page views, clicks and behavior, Crowd Science Demographics builds an audience profile including age, gender, income level and other demos that provide you insight to your audience.

Crowd Science can help you create a model of your audience that reveals more than the records of IP addresses and page views. Their audience measurement service is able to build deep, topic-area-specific statistical models of the demographics and attitudes of the visitors to your website.

Their research methodologies are as polite and non-intrusive as possible – they recognize the advantage of an engaged audience and the very obvious disadvantage of having one that won’t come back. Activating your website is a breeze. The data will be yours to keep and to use for any purpose, evil or otherwise. Whether you are a publisher, a blogger, an advertiser or a researcher, Crowd Science can help you understand your crowd.

Crowd Science is currently under Close BETA. However, they are very kind to give WebAppers readers 100 invitations. You can sign up with invitation code: WEBAPPERS. Hurry up!

IMG·2·JSON is a simple Google App Engine python application which extracts metadata from images and returns the results as a JSON string. To use IMG·2·JSON all you need to do is perform a request for the fetcher-script URL hosted on Google App Engine.

And then it will return the mimeType, width, height, byteSize and EXIF metadata extracted from the image (such as Camera Manufacturer, Model, Orientation, Date, GPS position, etc). I found it useful for developing web application that needs to identify, sort or find images. How about developing a search engine for images?

ShiftSpace is an open source layer above any website. It seeks to expand the creative possibilities currently provided through the web. ShiftSpace provides tools for artists, designers, architects, activists, developers, students, researchers, and hobbyists to create online contexts built in and on top of websites.

By pressing the [shift] + [space] keys, a ShiftSpace user can invoke a new meta layer above any web page to browse and create additional interpretations, contextualizations and interventions – which we call Shifts. Users can choose between several authoring tools we’re working to develop – which we call Spaces. Some are utilitarian (like Notes and Highlights) and some are more interventionist (like ImageSwap and SourceShift). Users will be invited to map these shifts into Trails. These trails can be used for collaborative research, curating netart exhibitions or as platforms for context-based public debates.

Notes is a Space that allows a ShiftSpace user to leave post-it annotations on websites. Highlights is one we’re still developing, which would allow a user to highlight text on the page. Some Spaces lead more naturally to an interventionist usage. Two such Spaces that we have implemented are ImageSwap, which allows a user to grab any image on the web and swap it in place of other image, and SourceShift, which allows users to freely edit a page’s HTML code.

When a user visits a modified (’Shifted’) webpage, the small ShiftSpace icon (§) pops up in the bottom left side of the screen. Pressing the [shift] + [space] keys reveals the ShiftSpace console. From the console, the user can browse through existing Shifts, choosing to enable those that might be of interest. Holding down the [shift] key shows a small contextual menu, allowing the user to create Shifts of her own. The user can then choose whether to share her Shifts or to keep them private.

Soundsnap is a nice platform to find and share free sound effects and loops- legally. It is a collection of original sounds made or recorded by its users, and not songs or sound FX found on commercial libraries or sample CD’s.

It was originally started by a small group of sound people from all over the world. Their common belief is that sounds and samples should be free for everyone to use in their projects, commercial or not.

Their users are a diverse mix of sound designers, sound artists, web game developers, filmmakers and music producers. Hobbyists and home video makers are welcome too. They encourage everyone to upload high quality sound FX and samples, helping them make every kind of sound available on Soundsnap.
