But this one's particularly notable because it happens as Twitter is still reeling from a denial-of-service attack last week that targeted a Georgian activist blogger but ended up knocking Twitter's servers offline for several hours. Other services, like Facebook and LiveJournal, were also affected by the attack.
The value to workers of having Internet access - in terms of research, communication, and speed - is far greater than the threat of lost productivity. Companies have a right to make policies and rules about personal use of the Internet, but blocking it during work is just stupid.
It is a web based service, computing platform, and communications protocol designed to merge e-mail, instant messaging, wiki, and social networking.[3] It has a strong collaborative and real-time[4] focus supported by extensions that can provide, for example, robust spelling/grammar checking, automated translation between 40 languages,[2] and numerous other extensions.[4]

"Facebook is where people go when they want to share, when they want to connect, when they want to reach out to the people they know,
Social search takes many forms, ranging from simple shared bookmarks or tagging of content with descriptive labels to more sophisticated approaches that combine human intelligence with computer algorithms[2] [3].
Social search or a social search engine is a type of web search method that determines the relevance of search results by considering the interactions or contributions of users. When applied to web search this user-based approach to relevance is in contrast to established algorithmic or machine-based approaches where relevance is determined by analyzing the text of each document or the link structure of the documents.[1]
Concerns
Risk of spam. Because users can directly add results to a social search engine there is a risk that some users could insert search spam directly into the search engine. Elimination or prevention of this spam would require the ability to detect the validity of a user's' contribution, such as whether it agrees with other trusted users.
"The Long Tail" of search is a concept that there are so many unique searches conducted that most searches, while valid, are performed very infrequently. A search engine that relied on users filling in all the searches would be at a disadvantage to one that used machines to crawl and index the entire web.
Benefits
To date social search engines have not demonstrated measurably improved search results over algorithmic search engines. However, there are potential benefits deriving from the human input qualities of social search.
Reduced impact of link spam by relying less on link structure of web pages.
Increased relevance because each result has been selected by users.
Leverage a network of trusted individuals by providing an indication of whether they thought a particular result was good or bad.
The introduction of 'human judgement' suggests that each web page has been viewed and endorsed by one or more people, and they have concluded it is relevant and worthy of being shared with others using human techniques that go beyond the computer's current ability to analyze a web page.
Web pages are considered to be relevant from the reader's perspective, rather than the author who desires their content to be viewed, or the web master as they create links.
More current results. Because a social search engine is constantly getting feedback it is potentially able to display results that are more current or in context with changing information.

he concept of social ranking can be considered to derive from Google's PageRank algorithm,[citation needed] which assigns importance to web pages based on analysis of the link structure of the web, because PageRank is relying on the collective judgment of webmasters linking to other content on the web. Links, in essence, are positive votes by the webmaster community for their favorite sites.
solid, lightweight product for business communication that could help workers (along with customers and clients) keep up to date with each other, and could also reduce in-company e-mail spam.

Thus, blogs, email, instant messaging, social network services, wikis, social bookmarking and other instances of what is often called social software illustrate ideas from social computing, but also other kinds of software applications where people interact socially.

Social computing can be defined as follows:
Social Computing" refers to systems that support the gathering, representation, processing, use, and dissemination of information that is distributed across social collectivities such as teams, communities,organizations, and markets. Moreover, the information is not "anonymous" but is significant precisely because it is linked to people, who are in turn linked to other people.
