Do other search engines use meta keywords

[ReSEOlve]

Just want to know even those Google states it doesn't use them is there any benefit from using them for the other search engines?

Yes there is there are a lot of Search Engines out there and some of the old ones still look for keywords.  Some SEO say to use them and some say its a waste, I always find that more is always better. Keywords can always help seeing that you need to know what to market in your text. So if you did the research and have keywords to implement why not add them into the meta.  But no Google, Bing and yahoo don't.
