Sharpen before or after downsizing or both?

When I downsize a 5DMKII file to a 1024 jpg on the longest side for posting on the web. Should I sharpen before, after or both?

Thanks

I sharpen before and select "Sharpen for Screen" in the export dialog box

Some people do both. Have you looked at the "Sticky"?

I will now Frank, I must admit I never really 'see' stickies.

Generally sharpening should be the final step in a workflow.
