I'd say Python is making great headway and I'm really not a fan of Ruby for reasons already outlined (cracks, etc.).
Java seems to be great, less issues than it used to have, but I'm not even remotely fluent with the basics, so I guess that's a point of great bias. I'd love to be, but I've had no time to be (we'll fix that later, I hope!). I still think Java is great for websites/webapps.
Perhaps Java is more widely used for LAN/intranet/infranstructure, which is where I have experienced it most, and it does exceptionally well there. At the same time it does, at times, have a heavy feel, but having built in features and Sun's lovely gift of identity management, etc., was sure to do that, I guess. Seriously, Java is great in itself, I just hate the sluggish and broken applets idiots keep putting on the intranets... I'm sure they'd be fine if they weren't poorly hacked together.
