/addcomment v.s. /comment is all about the relationship to the parent. /addcomment IMHO should be a PUT since you're telling me your updating the parent, whereas /comments makes sense as a POST. Just my two cents, but I'm not a fan of a POST with /add. POST already says create. PUT says update. /add is wasteful and confusing when you already grok HTTP verbs. If you don't really think in terms of HTTP verbs though, then /add reduces confusion. The more uptake REST gets, the more natural it'll seem.
