Yahoo slow in indexing websites?

[Aditya]

I have a website just 4-5 months and it is performing well so far with Google and Bing. However, looks like yahoo won't even listen to it. I can see some back links indexed by yahoo and it successfully crawled my website. But knowing fully well when bing and google are adhering my content, why yahoo wont?
any suggestions to make yahoo aware of my site and worthy enough to be included within organic search results?

Thanks

For each SE we need to plan our SEO strategies, try to concentrate on the things like title tags, meta tags yahoo still give weightage to these but Google doesn't..
