I didn't do it - didn't figure it was worth the money when you can get indexed and included in Yahoo search results for free... the backlink may help PR a bit but you can take that $299 and buy some good links and then alot of beer with the leftover $$$.
if it were a 1 time payment I may consider it, but as stated above you could get tons of qulity links for just 1 year in yahoo
A listing at yahoo directory is seriously worth the money, yahoo is PR8/PR9 and its YAHOO, means you'll get Yahoo SERPs Advantage, some boost in the google ranking algorithm of your site, PAgerank, Traffic, Popularity, Daily search engines bots crawl (way faster)...
i got my site included in yahoo directory free of charge. i rank top positions in google for a certain keywords (not all). In general, getting listed in yahoo assumes that your site is high quality.
Total BS. you are not gonna get listed on pr8 or pr9 page... its fine if you have extra cash... but for 299 buy lifetime links in other good directories
