Challenge: Facebook has massive scale, deep engagement, and the resources to launch adjacent features quickly.
vGrave Advantage: vGrave is purpose-built for memorialization, not a general social network trying to retrofit grief support. That specialization creates a far better user experience, stronger emotional trust, and a platform architecture designed around remembrance, legacy, and ongoing engagement. Even if Facebook adds memorial features, it will still lack vGrave's depth, sensitivity, and category ownership.
