It's getting worst everyday, my widgetbucks RPC (rate-per-click) is decreasing, now I'm suffering again from .02 per click which worst than my adsense. Widgetbucks publisher was informed about this issue about 6 days ago, hope Mpire is working on to get those CPC rates back to their week-ago levels.
I believe Widgetbucks is still the best alternative to google adsense, galaw galaw baka ma stroke 
UPDATE 4/06/2008: WidgetBucks' RPCs Rebounding.
Good news to WB publisher, RPC's is now back to normal.
