Some observations
• Be specific
• Internet is used for INFORMATION and for COMMUNICATION. RSS feeds serve the communication function. That means, opinions, bias, …these are valuable too.
• Esp news- V V Selective.
![Page 24: Rss Feeds](https://reader036.fdocuments.us/reader036/viewer/2022062704/55577304d8b42ace7f8b5391/html5/thumbnails/24.jpg)
Some Perspective• Internet has its limitations• Search Engines have their limitations• Individual users have their limitations• Not all websites have RSS Feeds• RSS Readers have their limitations• Esp. Premium content….which represents knowledge based
on research & deep thinking are still inaccessible via free resources.
• V V V selective….so shd not be dependent entirely on RSS Feeds.
• Other tools required….one such tool is Delicious.
