Correct consumption of information and knowledge base

People in the 21st century need to process large amounts of information to manage life processes. Now it has become much more difficult to do, since every day we consume a lot of information and quite often it happens that what we have consumed does not turn out to be useful for us. From a huge article on the forum, there can be only a couple of lines of really important information, and from the flow of messages in corporate messengers there are only a few that carry some value, and not the whole flood. Probably everyone would really like to get what he is looking for, and if all this could still be obtained without additional effort on the search, it would be even better in order to quickly see the latest information. For example, if we could see news from sites automatically by certain keywords or information from social networks that needs to be saved separately in order to return to it again after some time. Please share, maybe you use any knowledge bases to simplify the consumption of information and do they really solve such problems with the safety and delivery of the required data?
