What did you mean? If you mean your domain has appeared in Yahoo Directory search because the other website listed in Yahoo Directory linking to you, then it does not matter. The link from Yahoo Directory will be matter only if your domain is listed there.
Question not clear. But I found out that advertising in yahoo ad network makes your site be indexed in yahoo very fast.
It doesn't matter unless that software doing it right way. I always prefer manual submission to directories like DMOZ, Yahoo, BOTW etc..
I agree a manual submission to the larger directories like Yahoo give you the chance to be original and make sure everything is correct.
thnx to all.. it seems i can use a software for indexing in directories neacause i dont have so much time for manual indexing
We were just talked about Yahoo downfall (including slow indexing and bad ROI) http://forums.digitalpoint.com/group.php?do=discuss&discussionid=1148
It is better to submit manually to large directories like Yahoo because it increases the chances of approval.
It's better to submit manually, because some directories require image and e-mail approval and lot's of other information that regular software won't provide
It will took a couple of time before your site gets approved on Yahoo Directory. Mine is still not approved.
