Questions and answers sites have always been popular, and now that online interactions have been redefined by the social web they are just going from strength to strength. And in the event you are looking for one that is wholly devoted to Ubuntu (the Linux operating system that is quite standardized), you are treading the right site.
Here, you will find queries that are submitted and answered by the community itself. These are voted up and down by site users, and the most popular ones are obviously highlighted on the main page so that those who arrive on the site for the first time are able to see interaction among users in the best light. That is so because questions that have been favorited the most are probably the ones that have the biggest number of comments, and anybody can measure how the community works representatively enough through it.
Furthermore, you can see which ones are the most discussed topics by looking at the cloud of keywords which is provided on the main page. These include “Upgrade”, “Windows”, “mysql” and (of course) “Linux”.
