Here is much more applications, but I will mention only two, because on my point of view they are representing possibility for most of users (uninitiated :) users (delicious) and also professionals :) (citeulike).

Delicious is most popular and most using system for creating bookmarks. The main point of this system is to save, organization and common using favoured items exported from internet client. Users of del.icio.us indexing together sources and they are also tagging them. There is a possibility of connection between users blog and the del.icio.us. Very interesting is bookmark “inbox”, which presenting a tool to obtain a new bookmarks from different users and different categories. This page have a good perspective to compete with Google and others, because results here depend on people opinions and judgments, not on opinions of machines. We can see a big popularity of this service. For example Firefox have a special bookmark Add-ons for delicious.
And by the way, here is one very usefull blog about delicious - http://blog.delicious.com/blog/.

„2,526,079 articles - 2,198 added today“ it´s speaking for everything.
This site is mainly designated for scientist. In the results from this page users receive a post to full version of article or to the abstract of article and links to related categories, but also to other user, which are interested in the same area and their bookmarks. Users can choose of course RSS delivering and service supporting also pdf format .
Systems to organization and tracking a sources on the internet
Here is also much more applications, but I guest, that I choose all well know.

I guess everyone know this page, but how many users knows about possibility of channels, community, forums, sharing with twitter … Here is definitely more possibilities than normal users even imaging. It is up to us search for new possibilities on this page, because lot of are very useful. We can see here also connection with Google (on the first page, commercial on Google Chrome,…) . This webpage was puted on the list "The ten biggest failures of the last decade" in 24/7 Wall St. magazine and take the 5th place!! We can see a lot of problems with making the profit, and also a lot of penalties from recording companies for the showing a video-clips. In the other hand provider of YouTube, Google trying to make a deals with movie industry about possibility of showing the full-length movies on the YouTube pages. If the main goal of this kind of service going to be a profit, I think it will pretty crapy and here is also still possibility of migration of users of YouTube to another similar services, which are for free. Future wil show us a result of this service One usefull blog about this phenomenom : All about YouTube.

Technorati allowed make descriptions, common using and to tag a blogs. At june 2008 thids service was indexing a 112.8 million blogs. The main condition is to create your own account and registration. The very useful is possibility of “watchlist”, what means to create your own list, where will be a continuously and actually showed all posts which you like. This page is good choice if you would like to know about events in all around the world, and you would like to be first. I gues, that this is something similar to the twitter, but here is no limits to express what u have on your mind, but continuously is worst here. Anyway still good tool.

This is a tool for searching of pictures in database, which includes amateur and also professional photographers. The main criteria for searching on flappr is popularity. Users can choose also others criteria like actuality, tags, other users recommendation… This tool consist a lot of awesome pictures, it is almost unbelievable how many beautiful pictures are here. If users click on one of the pictures, than under the picture will show up a details about author of this pictures, and user can follow this author in other categories. If you are interested in pictures and photos this is heaven on earth for you. I think that this service have a very prespective future, because a lot of companies can find here a lot of nice and also professional photos, which can be usefull for their commercials and also is possibility for the photographers to become a shining stars.

Users taging and saving the sources to colections. What is different from others is a possibility to see in results not only results from wink, but also from Google. Now we can compare the results from stuff like google and results from folksonomies. Are they very different from each other? I would say, it depends from case to case. But mostly in my cases I found more useful informations in resulst which were based on folksonomies. I think the combination of folksonomies results and also resulst from web searching engines is like middle (gold) choice for users, which still are not very trustful to searching on folksonomies. Also one good possibility is a „wink answers“. This will show to user whole definition of a key word, but also a list of related term (of course with their definitions) to this word.

This application is very special in good meaning. Gravee searching for not only web pages, but also on blogs. The main criteria in tagging is that people but also a machines tagging here. Users dividing the sources to two main categories- relevant and irrelevant. I think that this application is something similar to the technorati. The main difference is that users here can be everyone, not only scientist.
