Blog is a spelling mistake
Blogger‘s own (lousy) spellchecker says blog’s a spelling mistake (and helpfully suggests bloc, Bloch, blows, or bloke instead). Ironic, ain’t it?
Btw, haven’t you felt Blogger has been pretty much abandoned lately? It’s feeling untended and clunky lately, not that it ever was particularly elegant — it’s just that obvious errors aren’t being corrected, obvious improvements (webcraft advances by the minute) aren’t being implemented.
