Surfing the Internet can be an interesting past time if used constructively. There are an abundance of resources on the Worldwide Web, some very high-quality, some less so, for doing research and investigations on a host of topics. I find that thoughtful, well-planned research on the Internet can be very worthwhile.
In addition, just roaming the Web for interesting stories, facts, and to view cultural events such as music concerts and literature readings are also very enjoyable. However, I find that when I haphazardly - without at least some semblance of a plan - roam the Web, I can get bogged down on frivolous, less than informative sites that actually wast my time.
Too much of this and soon time has flown so much that hours have been wasted. This is the negative side of less-focused Internet browsing and it can be very unproductive.
