The European PlayStation website will introduce Trophy comparisons and leaderboard support in mid-July.
Sony's portal manager Emmanuel Orssaud announced and detailed the changes on the blog (spotted by vg247), claiming these additions to be "much-requested" by you, the community.
"My Trophies - Compare with your friends" will show the awards earned for particular games and pit them side-by-side with a friend. Similar data will be the basis of a leaderboard that tracks not only how well someone is doing, but how well they have done previously, and whether they've climbed or fallen. Fun graphs!
These planned changes are announced as the US PlayStation blog adds mobile compatibility, so it can be read on iPhones, PSPs and mobile phones.
