People make personal information increasingly available into online services. A study done by Bovitzin shows that 70% of young and 77% over 35 years think that their private information should be kept unavailable. At the very same time over half of these people are willingly providing they private information to online services. Reason for this behaviour seem to be that people believe information exchange as integral part of social media. Interesting to see how this develops as utilization of shared data increases and both positive and negative effects become visible.
Open data provides new bulk source of infromation that can easily lead to new innovative online solutions as barrier of entry is getting lower. Ammount of open data sites is increasing rapidly as governments see increasing utilization beneficial for businesses and thus local economies.
Scoopshot is excellent example of information collection with crowd sourcing. Similar approaches are utlized in review sites, which make their users as content providers. This enables better coverage of online services also in not so dencely populated parts of real wolrd.
