The folks at Wordpress.com announced this week that they would be offering a premium option to users which would remove Adsense ads from their Wordpress hosted blog. The Ad-Free upgrade will be offered for a yearly charge of 30 credits (which appears to be dollars).
This is a good move in my opinion and one that I feel should be offered by any service that displays ads on user generated content. A value added service for a reasonable price….although I will always recommend a self hosted option.
