Josh reminded me that you can post comments via RSSBandit and so I gave it a whirl on my own post. All I can say is: supa sweet.
Munish pointed out in the comments on that post that the latest build of RSSBandit is 184.108.40.206, not 220.127.116.11 as Help | About reported to me. The odd thing was, I had 18.104.22.168 saved in my temp directory from my installation attempt last night. So I smacked my forehead, what with my aborted attempts at installing it last night, I must have still been running the older version.
Now that I am actually running 22.214.171.124, I should correct myself. I am very pleased by the changes since the 90 build.
Several of the small UI quirks I mentioned have now been addressed. Apparently I'm not the only person anal enough to be bothered by the title of the Options dialog being Preferences. I was pleased to find that F1 opened up help... but interestingly enough, I don't see a way in the UI to get to the help that F1 brings up! The Help | Online Doc option goes to the website.
And the best of all is <drum roll>... left clicking on a link opens my default browser! The option that used to previously control the behavior for right click | open in new window now controls left click. HUZZAHs all around!
I'm still stuck with delete being a no-op, which bugs me a significant amount. But I opened a DCR (the URL is conveniently accessible from the Help menu, although it opens in a blasted tab :-).
I don't think I'll stop using Newsgator. The Outlook integration is just killer for certain types of feeds that I read. But I'm definitely warming up to el bandito.
[Update 9:48PM] HOLY COW. In addition to showing the comments as sub-items in the view, RSSBandit also expanded the trackback to my previous post. Although... it's not working for other trackbacks that I can see... but still, the potential is making me excited. Time to go lay down.
