Google Groups is a free online community and discussion group service that offers the Web's most comprehensive archive of Usenet postings. Google Groups can be monitored using RSS feeds. In order to monitor a specific newsgroup simply add "/feed/msgs.xml" to the end of the Google Group URL. Add the new URL to a newsgroup reader and receive updates each time a new post is added to the newsgroup.

Ego Searches

Photo credit: Gina Smith
An egosurfer is one who surfs the Internet for his own name, to see what, if any, articles appear about himself. Ego searches are free and simple searches designed to monitor blogs and news portals for mentions of your company, product, competitors, or other specific keywords. Conducting ego searches, not only allows you to stay informed, but also allows you to maintain a strategic advantage over competing companies. A number of new Internet services are freely available that make these 'ego searches' painless and easy.
Many of the services allow you to create a keyword based feed. Each time new information containing the keyword appears in the searched resources, the RSS feed updates.

Podcasting and Podcatching

I wasn't going to even list this one, as it has caught on so rapidly that nobody wants to hear anymore what podcasting is, but then I gave in to list here after many not-too-obvious applications, as a reference for those who have not yet been exposed to this wildly popular and effective use of RSS. "Podcasting is the distribution of audio or video files, such as radio programs or music videos, over the Internet using either RSS or Atom syndication for listening on mobile devices and personal computers. The term podcast, like "radio", can mean both the content and the method of delivery. Podcasters' websites also may offer direct download of their files, but the subscription feed of automatically delivered new content is what distinguishes a podcast from a simple download or real-time streaming. Usually, the podcast features one type of "show" with new episodes either sporadically or at planned intervals such as daily, weekly, etc. In addition to this, there are podcast networks that feature multiple shows on the same feed."
(Source: Wikipedia)
Podcasting is all about allowing you and me to listen to our favourite audio and video programs wherever, whenever and on whichever device we want.

Video editing

Thanks to RSS grassroots collaborative video editing may soon become a reality for many. Kent Bye has been working at such an idea as well as the guys behind some of the hottest new online video editing sites that have recently launched. RSS is a key component in all these tools as it helps those working around a theme or a specific project to maintain themselves updated with new clips posted and available for them to work on.

Swarming
The term swarm (schooling or swarming) is applied to fish, birds and insects and describes a behavior of an aggregation () of animals of similar size and body orientation, generally cruising in the same direction (source: Wikipedia).
New online services are emerging that will allow small and large groups of people to remain in synch with each other even when not in close physical contact. These services will invariably employ SMS text messaging, email and RSS as their key channels of spreading communications in the fastest and most effective way to their interconnected groups.
Stay tuned.
X-events
X-events are a new and more effective way to run live events that will extend the event interaction to much before and after the actual event. Via the use of new media technologies including RSS, blogs, P2P, personal media aggregators, forums, wikis and other tools, the event organizers of the near future are in for banking lots of money if they understand that the name of the game is in the extended, interactive event in which the live event (online or not) is only but one of the many components and services offered.
