Jewish FReepers, if observant, would be mostly comfortable with your blessing. As long as you are not blessing them to convert to your religion, or invoking a god they wouldn’t pray to. If you left it as a ‘generic’ blessing for some positive thing like health, success, wealth, good furtune (etc.) it would be fine.
