Why not just practice reading it "I love you"? A more charitable interpretation of the writer's intent and less likely to get you so frustrated.
So now you have a very basic UI component (which is sadly not very innovative, being just a different version of Facebook's 'like' feature) but people are likely to attach two different names to it. Notice, by contrast, how FB constantly reinforces the use of 'like' as the operative verb. You don't hear anyone saying 'thumb-up this post on facebook' even though everyone recognizes the thumbs-up symbol as being synonymous with liking something.
I don't really think of ascii art as a form of basic ui function though...
That said, the spurious asterisk in 'diaspora' does look pretty inexplicable, and needs way too much explanation to people who haven't drunk the kool-aide already. Add in the fact that 'diaspora' is never capitalized, even if it begins a sentence, and you're kind of way off into the eccentric orthography zone.
