Recently I have submitted my website
www.meadowshplc.com to yahoo directory. It took them 7 days to place it there. There should be no problems with most websites imho. They have those restriction to have them in case of something exceptional happens.
After 2 weeks yahoo gave me 23 links (dir.yahoo.com, ca.dir.yahoo.com, in.dir.yahoo.com, sg.dir.yahoo.com, asia.dir.yahoo.com) so as far as links are concerned it looks ok. The question of course is if they really helping my serps? I am on second position in my 2 keywords (used hplc, refurbished hplc) but i have been in yahoos top ten before so its still not clear to what extend it helped me.
One thing i noticed is that Yahoo search shows now yahoo directory description for my website not original meta tag description like before.
