Information about schools and school systems is highly important to families who are weighing a home purchase. Trulia offers abundant information about schools right on each property listing page! Consequently, our search engine optimization measures drive more and more people to these pages.
I would not classify most school-related questions as spam. In some cases the questions do not originate from persons actively engaged in a home search, but the fact that they are using Trulia as a resource for information opens a door to the possibilty of those people referring home search information to their friends and family who may be engaged in property search.
Scott has some sage advice ... flag questions that you think we should remove. These questions will be obvious. In the meantime, we have the matter under study.
Our web designers are making improvements every day that enhance Trulia users' experience here. The new MEMBER SEARCH is a great example! Have you tried it? You can search Trulia Voices by area, by name, and by keyword (including school ;-).
