There is a huge list of different types of linux distributions available today with choice to choose any one according to one`s need . Some distributions purely suit home users and others do not at all . Every linux distribution presents variety of problems times and again . To overcome these problems every linux distribution developers offer some sort of support offered through forums,documentations and IRC help/support rooms.Those projects which offer any kind of support to the end users get more loyal users and survive for longer times as compared to those who do not bother to offer any help.
The success of a support system offered by a linux project depends on how well organized and systematically maintained it is and then delivered to the end users. It also depends on how best targeted it is according to the users demands and knowledge level . Another key point is the easy access of users to such help system and the quick response of the support team to emerging issues with easy and adoptable solutions.
Communications skills of the support team is of the highest importance because home users are not linux experts and gurus and they easily get discouraged if the support team treats them unprofessionally or ridicule them for matters which may be of little value for the developers but of great importance for home users.
Saying all this I will leave aside the good and bad things of Unity Linux at this moment and talk about its help and support system briefly. Unity Linux is a relatively new project and still at RC level of its development . But it has established a growing number of users because of its solid, stable & systematically maintained help & support system . Unity team members and developers try to help users at their level of knowledge and understanding without posing as "I know everything" .
As I said above if a linux development team follows simple rule of caring for their products users and does it in a methodical way there is no doubt that such project grows and have a long life. Unity Linux team has realized this core concept and if they stick to it I see this project as a potential Best Desktop Linux Distribution (DLD ) for home users of all times.
