Well these kinds of websites are already famous and it might be hard to create websites like these again. Creating these kinds of websites would not be easy and also the toughest thing would be to compete with such websites. People are very loyal and addicted to these websites and would not go to other websites. But question and answer websites are not like that. No one needs to be loyal to question and answer website. The websites which gives you great user experience and helps you in getting answers to your question is good. And people don’t mind shifting from one website to another. People go on to whatever website they find better, so there is no such loyalty. That is why people opt to make question and answer website which is a great idea.
The question and answer website is not that competitive and yes it is more that competitive. Now that sounds confusing but it is correct and lets see how that is. Lots of websites based on the same theme can be very competitive and we would have to win against all of them to make it to the top. But the question and answer website are only a few of them and that is why it is not that competitive. But the problem is that the only few of them which are online are very famous and with lot of users. These few websites have been here for a long time and people are familiar with them. Now this creates a big competition as we would have to hustle up with these few big boys. So it is kind of easy and also tough. But this website is a very good concept and when it reaches the people and when users post questions and answers it gives you a sense of great achievement.
People build question and answer website not for social service and neither for fun. But they build it for earning money. Yes, everyone wants money. Running a website is not a joke at all. And particularly websites which has lot of visitors on a daily basis requires lot of attention and lot of money to run. The domain has to be kept intact and that requires a lot of money. You cannot host the website on a simple server because when lot of people view the website from different locations and at at the same time it requires a lot of bandwidth. One has to go for dedicated servers and this would take a lot of money. Question and Answer Website if succeeds then it would require server which is not shared and has sufficient bandwidth and should be able to process the data very fast.
