You could be a little more specific.....

Assuming MyPoints really has become less useful and isn't just having (big) teathing problems then it depends on what you want it for:

If you want to earn rewards from Shopping then you still have a reasonable range including Goldpoints, Greenpoints, Clickrewards, Airmilesmart etc etc (see my shopping rewards comparison table for the main programs and their partners - I haven't updated MyPoints yet because the jury is still out on the changes and if they are intentional)

If you want free points from reading email to convert to Hilton points then you are left with e-rewards.
