I'm working on a news aggregation system inspired by reddit.com
Site can have multiple categories created by users. I would like to display as many categories on front page as I can, without sacrificing style, usability and design.
two obvious choices are:
Vertical list on left side - Advantage: I can list lots of categories, as vertical placement give me unlimited amount of space - Disadvantage: Based on text size of category, the looks and spacing between categories and content are compromised
Horizontal list on top of site - Advantage: Does not compromise design - Disadvanage: Limited space depending on User's screen resolution
I'd really appreciate your input on this. What would you recommend I do?
