So, to summarize, SEs necessitate a huge organizational effort, provide the user
with too much noisy information, but are useful for a one-time shot for quickly
needed information. DLs, on the other hand, require a modest support effort,
provide the user with focused information, but have to be made available
beforehand while excelling in quality and ease of use. It is important to note
that these two paradigms are neither conflicting nor exclusive, but are
complementary in nature.
