sharing

People share knowledge selectively or release knowledge selectively. If any knowledge or information is useful and important, it should be shared immediately. Sometimes knowledge or information shared belated is like rotten food served to a hungry person. Some people write books after retiring from service, these people are cowards and dishonest people. They could have been of some cause and use if they did share immediately. They are not historians, they are important people in public life. Of course some people don't find time or they may not have skills to write a book, or resource's to publish. With access to technology there are different means to share, it need not be just books, other options are like, blogs, podcasts, video recordings, mind maps, etc. Some people write for creating sensation or for earning money. Some people share the personal life of others, without their consent too.
