If you are looking for attractive themes for their personal blog, I venture to recommend FREEmium WordPress, a WordPress theme that I found very good and its structure has been ordained as a whole, as smoothly into the design.

Features:

• XHTML 1.0 Transitional
• jQuery menu
• quick submitting to web2.0 websites support
• flickrRSS plugin support
• threaded comments support
• feedBurner subscribe via email support
• a lot of advertising spots (125×125, 120×600, 300×250)
• 2 widget ready sidebars
• free for commercial & non-commercial use
