Words cannot express how frustrating the new blogger interface is. If you read the hoopla surrounding it, it's clear that it's been a completely technology and design driven effort, rather than a market driven one - and it shows.
Using it to actually publish a blog is a bloody awful nightmare - it's light years behind how simple, intuitive, clean, and context-rich the old interface was. But hey, it spits out perfectly compliant and well-formed html, xml, etc.
