Please give yea or nay opinions

Have been having discussion with various people.  I use LibGuides in my library to create subject guides and newsletters.  But I know other people who use it  make simple websites or search interfaces for archival collections.  So this says to me, LibGuides is a content management site. Especially when you can add widgets to do polls and search boxes and analyze hit data for pages.  But several folks are trying to convince me it is not a content management system.  What do you think?  Is it or isn't it a content management system
