Do Link Pages and Directories Serve Link Popularity Purposes?

People often resort to submitting websites to directories or link pages because they think that these sites command good link popularity and therefore, will provide them with a boost in rankings. But let’s come to think of it, do they really serve their purpose?

While they provide new channels for referral links, I think the quality of links of these directory pages or resource/link pages are diluted due to the numerous links they’re pointing to but less links point back to them. In fact, search engines haven’t indexed some of these pages because of lack of internal linking taking place.
