What really gets to me is users complaining about web-based message boards on Orkut. They say things like how it isn't powerful enough, and how they can't keep track of communities. And I realise that this functionality must have been implemented a bazillion times everywhere.
I suggest that these people who write messaging software write Weblog-to-NNTP gateways. Then host authenticated NNTP servers on their site. That way, you can read comments using a full-featured client that isn't sucking up the server's resources. Not only that, you get real features. Like real threading, scoring, killfiles, your favourite editor, spell-checking, sane follow-ups, and a host of other wonderful features.
"But Simon," you cry, "nobody uses news readers anymore! It's all about the web!" Sadly, I admit that people are flocking to web-based e-mail services; so web-forums are really just difficult to find, hard to search, web-based news services. But if you ran NNTP on your machine, why you can also serve up a web-based news reader. I mean, the Horde project has its web-based e-mail client, why doesn't it have a web-based news reader? Well, whadaya know? It does.
