Flickr is a web2.0 service which provides users with an account so they can host and share their pictures online and short videos. Flickr can be used simply as an online photo album where users share pictures with their friends and family via their photostream and is used in this way by a significant number of users.

By promoting the tagging (which I explained earlier,) of pictures and the use of geotagging, (tagging a picture with it’s GPS location, which is often done automatically by a mobile phone;) Flickr, enables users to connect with each other. Users can find pictures uploaded by people who have tagged their pictures in the same way or have uploaded pictures from similar locations. Therefore, connecting users in different ways, all of which are relative to their own pictures.

Flickr promotes communities within it’s service using the groups function. The group function enables users to join an existing group or create a group of their own.


YouTube is another web2.0 service which provides users with an account so they can host and share their videos online. YouTube is a web2.0 phenomenon which has become ‘the place’ on the Internet for people to share their videos. Users require an account to post their videos and like Flickr these accounts are often used as ways of sharing videos between friends and family.

YouTube enables users to comment on videos, to show that they ‘like’ the video and it provides users with the ability to easily share videos in a variety of ways, including via email, FaceBook and Twitter.

YouTube doesn’t rely on user tagging to identify videos, it also uses the number of times a video has been watched to rank it under any particular search criteria or tag. Therefore, it uses it’s own community to validate the value of a video to each individual tag. While also providing further validation by indicating to a user how many people have ‘liked’ the video and any further comments users have made about it.

By using it’s user community to promote and share the videos within YouTube, it is easy to understand, how, from time to time, YouTube videos become ‘viral’ and spread across the Internet like wild fire. This is simply a symptom of the success of the service and it’s users.
