"Memorialize, Honorable, Comfort" are all great descriptions for what the site does. When I paid for the traditional newspaper post, it ran for a single day. If you happened to read the paper and obituary section that day, you may have seen it.
An online memorial sounds more aligned with what I wish I could have done. Moreover, the ability to send out a link to family and close friends is a better way to keep others informed about services and locations.
