Currently the message you get when User:Foo writes on User_talk:Foo is:
| Foo mentioned you on the Foo talk page in "Bar". |
This should definitely mention that it's a user talk page (and similarly for other namespaces), e.g.:
| Foo mentioned you on the Foo user talk page in "Bar". |
It should also special-case for when a user is writing on their own talk page, which is quite common:
| Foo mentioned you on their user talk page in "Bar". |
| Foo mentioned you on his user talk page in "Bar". |
| Foo mentioned you on her user talk page in "Bar". |
