Getting a digest with a lot of untrimmed posts is bad.   It takes forever
to try to find the one or two sentences of new content amongst all the old
content that you must scroll through (again).  Often you miss the one or
two fresh lines, especially when the post has like 10+ replies re-quoted
for the tenth time.

 Also, when traveling and using a slow or weak internet connection, these
Clunker Digests take forever to load, or sometimes the connection drops off
after you've waited and waited, knowing much of what you are waiting
through may be something you may have already read and commented on...

   Also, some POP servers (I think that means something, I know one of my
local email addresses IS a POP server, or something) have 'message
quotas'...and mine often tells me "message quota is approaching limit.
then Limit exceeded," until I go through my inbox and delete some.. Two or
three days of email, with  a few digests containing a lot of lazy untrimmed
posts sometimes fills it up and they stop sending to me.

   If you are going to take the time and trouble to compose a meaningful
reply to the list, you should take a second or two more and make sure you
are sending the reply in a way that it will get read without everyone else
having to trim off the stuff they've already read, sometimes over and over
and over and over........

  As a sometimes digester, I certainly  appreciate having the messages
contain mostly new content....especially the often esoteric discussions
like why a .002 ohm reading off your Hell-sender might fool your Wobbly
widget into....or what the sidewall load reading is on a BFD 25" off-road
M+S tire....grin.
