The ease of searching through public documents makes this tool very useful! I can't think about anything that would make me want to switch away from it at least right now (unless you're looking into other databases). It's great if someone wants access or needs help finding something in particular they are interested/looking up - but not so much as an end user themselves because there isn’t really any way around having your own knowledge base built by hand first before using such tools effectively anyway; however some people may find them helpful when researching certain topics / issues related directly towards their industry work area(s) though nothing wrong wih trying out new things every once & awhile either just like everyone else does :).
