I am using the Twenty Eleven theme. It has all the widgets in the location where I wanted. The simple and not busy design. It is one of the default themes used by WordPress, it should be more reliable and stable than other themes. I can choose the dark background to make my contents standout.
Twenty Eleven Standard, Aside, Gallery, Image, Link, Quote, Status
In additon, the 2011 theme for WordPress is sophisticated, lightweight, and adaptable. Make it yours with a custom menu, header image, and background — then go further with available theme options for light or dark color scheme, custom link colors, and three layout choices. Twenty Eleven comes equipped with a Showcase page template that transforms your front page into a showcase to show off your best content, widget support galore (sidebar, three footer areas, and a Showcase page widget area), and a custom “Ephemera” widget to display your Aside, Link, Quote, or Status posts. Included are styles for print and for the admin editor, support for featured images (as custom header images on posts and pages and as large images on featured “sticky” posts), and special styles for six different post formats.
