Or has it not?
The comic that Jackal posted reminded me how being cynical and scathing is usually a badge of honour on Internet message boards, a clear sign that you're (supposedly) smarter than the average fan of whatever it is you're talking about. Has anyone found their stance on certain topics has changed since joining an online Forum?
Of course, the biggest change for most people is probably how they stay in touch and there's probably a lot of people who are doing so almost exclusively through online means. I'm glad to say I'm not one of those people, but there are a few friends I'd probably have lost contact with if not for email and the like, particularly those who have moved away because of their jobs.
One of the most significant changes for me in terms of my hobbies would be how the Internet, as a resource, has made conquering video games just that little bit easier. I remember spending hours with my Dad trying to solve all the levels in the original Lemmings. Now there's solutions for every single level posted on YouTube. From guides to video walkthroughs to cheat codes to all the unofficial game add-ons various communities are making and online play, the Internet can certainly enhance the video gaming experience.
