Wikipedia goes with "Flagged revisions": Emphasizes importance of discipline in Crowd Sourcing

Crowd-sourcing to create an online repository of data/information has been a masterstroke from Jimmy Wales, the founder of Wikipedia! However, monitoring content in flow and validating data to be “clean” is key to building credibility. A little bit of censorship/discipline of data may actually favor Crowd-sourcing and content democratization!

Wikipedia, the online encyclopedia launched by American entrepreneur Jimmy Wales in 2001 with the idealistic intention of being an online repository of all human knowledge, announced this week that it would have to abandon one of its founding principles. To combat a growing amount of vandalism on the website, all entries would be edited before they go up on the site. Wiki announced this on August 31st and will conduct a pilot run over the next fortnight to assess the data validity, cleanliness on these lines.

Previously, any user was allowed to make – almost – any change to any entry: this was hailed as part of the democratizing power of the internet. But a sharp increase in false information – particularly in relation to people still alive – has forced a rethink.


How did the Wikipedia work before?


Wales has been feted as a brilliant business mind and social innovator for tapping into a popular impulse to add to public knowledge that few people knew existed, and even fewer publicly predicted.

Wikipedia still works largely by allowing anybody to login as a user and click on an “Edit this page” tab at the top of an entry. From there it’s simply a case of making changes and saving them, albeit according to a policy on “biographies of living persons”.

Any changes are then filed under the “Edit history” of the page, and the IP address – a numbered identity that shows where the change has been made from – is also kept on record. Pages that contain unverified information are highlighted.

Wiki introduces “Flagged Revisions”

The new policy is referred to as “flagged revisions”. It allows editors to adjudicate (mainly through reference to other news sources) on changes made to the pages of a living person. The flagged revisions will be rolled out by September15th,2009, and Wikimedia, the non-profit organisation that runs the website, will monitor users responses over the trial period.


A team of “experienced volunteer editors” will oversee amendments to such pages. “We are no longer at the point where it is acceptable to throw things at the wall and see what sticks”, said Michael Snow, chairman of the Wikimedia board.

And Mike Peel, its UK spokesman, clarified the intention: “Anyone can continue to edit these articles, but the work of inexperienced editors with less than three days’ experience will be subject to review by more experienced editors”, he said. “This is our attempt to create a buffer to ensure that editors do not commit acts of vandalism.”

Microsoft and Apple ready for war in portable media players

The war of portable media players has just gotten hotter!




On 24th August 2009, Microsoft anounced the touch screen version of the Zune portable media player which was announced on 26th May, this year was ready for launch and has been christened Zune HD.According to a report on Cnet, Microsoft will launch Zune HD’s sales campaign on 15th September at a price point of USD219 for 16GB and USD289 for 32G in 2 color options of black and platinum. Amongst others, Zune HD will offer several features that are not found on the iPod Touch, including an OLED display, HD radio, and high-definition video playback (using an optional dock accessory). Other new fetures will also feature Internet Explorer Web browser to work hand in hand with other Wi-Fi features (song sharing, Channel streaming, and Zune Marketplace browsing).Zune HD’s browser is optimized for the touch screen with an onscreen keyboard, but there’s no word on whether it will be capable of streaming Flash media (used by sites such as YouTube and Pandora), a capability that is currently lacking in the Safari browser for the iPhone and iPod Touch.Another interesting feature of the Zune HD will be it’s ability to integrate an HD radio tuner which can also transmit artist and song data, very useful for it’s existing FM radio song-tagging and download feature.Other regular features like a photo viewer, games, podcast management, and Zune Pass music subscription integration. Another significant improvement compared to Zune’s previous models will be it’s battery life. Microsoft said that it can have 33 hours of music playback and 8.5 hours of video (with Wi-Fi deactivated). High battery life will be significant since Zune’s previous models are none other than their poor battery performance.Microsoft also plans to dramatically beef up the video download selection of its Zune Marketplace online store, and use the improved storefront to power the movie and TV downloads available to the Xbox gaming console. The new storefront will support movie rentals that can be transferred to Zune hardware (similar to iTunes movie rentals) playable from either your computer or from the Zune HD.


If Microsoft was trying to steal the thunder out of Apple’s media event on 9th September, it almost succeeded. Almost! Apple’s reply came barely 48hrs after Microsoft’s declaration. Zune HD would be met with a fight and Apple would launch the newest versions of iPod Nano and iPod Touch to counter Zune HD! The big story would be the addition of Cameras to both the iPods! Also featuring would be the introduction of iTunes 9 with elements of social networking built into them. Rumours have it that Apple’s iTunes could carry support for Blu-ray discs, visual management and rearrangement capabilities for App Store software.
