I don't think it was any ruder than the OP Milly imo, though maybe it does come across that way to others.
"I agree with Twigs that it's somehow nicer to read a report hosted within OM - perhaps the external links somehow erode the 'OM community' and are perceived as self-promotion?"
Exactly that , imo.
I use OM to read input on OM, if i wanted to read blogs i'd search them out.
Btw, i always host my pics on Tinypic, there's no faffing that way, i'd probably never post a pic here myself if i had to go through the OM pic facility.
