It uses Twitter hashtags and wiki style to bring news from Saudi arabia but allow people to create/edit the newspaper article/columns ..
A somewhat similar idea : [url removed, login to view] (without wiki)
So to explain in more details:
1-I want a somewhat similar website which is based on mainly active Twitter hashtags/Trends in Saudi Arabia and posting them as news ticker/scroller in a modern attractive and well organized way and [url removed, login to view] and videos should show up with the news ticker as in here : [url removed, login to view]
2-All the reference features should be replicated into my website.
3-People should be able to interact with those hashtags/Trends from the website as in the reference one.
4-The most active hashtags can be selected to be written about in separate wiki style articles , can be edited by anyone but has to be moderated by admin, similar to Wikipedia style .
*Those should look well fitted with news ticker
6-I have some other thoughts but those are the basics.
7-It should be in Arabic (right to left orientation) - use google to translate and I can help translation.
