Another interesting shared media server is Flickr, which hosts millions of photos. Just like Youtube, usability community exploits the underlying framework Flickr gives, i.e with discussion threads and annotation pins. Flickr uses clusters (i.e usability, usercentereddesign, ux, interface etc) for categorizing the submissions. This form of grouping lets users see a set of blocks defined under a specific tag.

So why do people need Youtube and Flickr to post their findings, ideas and "hate submissions"? There are several reasons behind that.

• Youtube and flickr provides what current bug reporting systems do (can?) not
• People need different media to submit their bug reporting rationale
• People need to promote usability, user centered design, usability engineering and such parameters, and they don't just want to use blogs with limited feature sets.
• Organizations need to tell their customers that their product is not really awesome and fascinating, but also usable and not feature-bloated.
• Companies try to come up with some visionary comments in their CEO/CTO/CIO blogs. Since "usability sells", what items do you think is well suited for this kind of job? Usability, of course.

So what does Youtube offer? Let's have a look at some interesting links I recently harvested from Youtube lately.

• How eyetracking testing takes place. Some of these posts include the videos hotspot maps generated during the tests.
• A post from usabilitymagazine.com shows how a test subject fails (male, 31 yr old) to find the correct link to redeem his miles.
• Can you show how accessibility of web pages work?
• Cross dimensional gestural interaction techniques
• Special focus: Voting machines
• How can you perform a usability testing?
• A Pardus Linux user gives supplementary information in a bug report

I leave it to the reader to find out videos on how well a product performs in terms of usability (new Microsoft touchscreen product), German usability test video showing a paper prototype (or paper mockup), thinking aloud tests and amateur usability testings.

How about Flickr? I didn't have some time to check all Flickr for interesting posts, however the following can be quite interesting:

• Have fun: World Usability Day Cake
• Show me your poster
• Show the final part work of a paper prototype (Since paper prototyping needs time and re-iteration, it may not be suitable for videos)

While Flickr is A) less overhead, providing a fast response, B) suitable in showing the evident problems on a device C) usually used to show good usability experience, Youtube is A) rich in content (both video and audio), has tendency to show bad usability experiences or usability issues.

Putting some quantitative work in the ideas above, one can start with another research area.
