Agree with Artful Codger and Mark Clark -- I much prefer serif to sans-serif (especially with the larger font size).
However, many web designers these days agree that Georgia is a better choice for Web use than Times Roman.
See, for example, web-savvy typography:
The old guideline about only using sans serif fonts on the web because they are more legible
is no longer true. Now you can design without fear using serif fonts on web pages. The most
popular choice for a serif font is Georgia with Times font as an alternative. However, Times
font, designed for print, does not work as well as Georgia.
