blogging software

[Daniel Barlow]

My brief evaluation of available blogging software "platforms" has
drawn the tentative conclusions that all the options are one or more
of

(a) hosted
(b) written in php, which wouldn't be a problem per se, but seems to
    invite a certain less-than-robust attitude to security
(c) undermaintained or unmaintained
(d) Movable Type (which for this application would be expensive)

and as I already have a phpbb installation to worry about, I'm loathe
to add another drive-in sql injection hole on any systems I have to
care about.  Any suggestions?

Requirements are

1/ new entries and entry editing through web forms interface
2/ multiple authors, each with own username/password
3/ comment support, preferably with simple comment moderation system
4/ vaguely pretty or easily prettifyable
5/ RSS
n/ if it can be hacked out the wazoo, that's good.  if it doesn't need
   to be, that's better

Sublogs and topics and stuff I can live without.

I don't seem to be finding anything that does enough of this stuff
out-of-the-box to make it worth learning my way around unstead of
inventing a wheel of my own.

Recommendations, anyone?  No, "edit by email" or "ftp the new entries"
is not an option here.  Yes, I too prefer to use a real text editor.
No, that still doesn't make it an option here.
