I use Google Groups, as since I switched to the Mac I still miss
Outlook Express's newsreader (terrible, I know) and haven't found a
newsreader to my tastes yet, but Google Groups is fast becoming
useless for posting anything - I often have to try 5 or 6 times to
post, each time it waits an eternity then times out, and after 5 or 6
attempts it just gives up and grays out the Send button. Grrr... Any
Mac people on here can suggest a good newsreader for me??


Not on a Mac, but this page lists some possibilities for you:
