I just and took a look at the recent Dot Net Rocks show, as a way to look at "what the market is thinking about". I got some interesting responses from looking at the titles. I haven't listen to all of them (not by far), but I won't let that stop me from commenting.

• Adam Nathan on Popfly and Silverlight
  Not interested at all. Something that belongs to another planet as far as I am concerned. Combining Popfly (some sort of purple duck, I understand) and Silverlight puts it on the far reaches of Saturn, as far as I am concerned.
• Miguel de Icaza and Geoff Norton on Mono
  Defiantly interesting, I have been keeping an eye on Mono for a while, I am waiting to see how it works on the Mac, and I argued for Mono based deployment in several projects in the past. EC2 + Mono seems like a very interesting option.
• Andy Leonard on Unit Testing your Database
  Seems interesting, but mostly my answer to that is: Use in-memory database for that. Oh, and don't use SSIS. Rhino ETL is trivially testable, by the way.
• Kirk Munro on Powershell and PowerGUI
  Not interested in PowerShell beyond the most cursory of glances. If I want scripting, I got Boo.
• Simon Peyton Jones on Haskell and Functional Programming
  This is something that I have yet to listen, but it is interesting, mostly because it is a totally different mind-set than the one I usually use.
• Les Pinter Looks Back
  That was a fun show, not technical content, but really good to listen to it.
• Aaron Skonnard puts BizTalk and WCF Together
  I get the shivers just thinking about the subject, next.
• Sahil Malik Shares the Point
  And I'll keep on going missing the point.
• David Aiken on Bridging the Gap between Dev and IT
  This looks like an interesting show.
• Steven Lees on FeedSync
  Not interested, I even took a look at the description to ensure that I am not interested.
• Kathleen Dollard on the Evolution of Software Development
  That was a fun show.
• Ken Levy on Visual Studio Extensibility (VSX)
  I need to be interested in that, because I have a chapter about IDEs that I need to write, but... that is not an interesting topic to me. Go write in notepad.
• Jeff Prosise Goes Deep on Silverlight
  Did I mention that it is not interesting?
• Joe Duffy on the Task Parallel Library
  That was a good show, and something that I actively looking at.
• Richard Campbell Tells All!
  Very good show.
• Jeff Palermo on ASP.NET MVC
  It was a good show, but the topic is not interesting, as far as I am concerned.
• Gael Fraiteur on PostSharp
  PostSharp is something that I keep looking at, haven't found the need for it, but it is an interesting project, and surprisingly outside my usual circles.
• Tomas Petricek on PHP in ASP.NET and Silverlight!
  Yawn, yawn.
• Open Source Panel Discussion at DevTeach, Vancouver
  I refer to this episode as the "if loop" show.
• Naveen Yajaman on Visual Studio Tools for Applications
  Through this show, I kept thinking: Or they could use Boo, get everything that they want and not have to pay "undisclosed" amount in licensing.
• Colin Miller and the .NET Micro Framework!
  Interesting in the abstract, not sure of its utility.
• F# Moves Forward
  I have this low level urge to look at F#, but I am just not interested enough.
• Dot Net Nuke Discussion Panel
  Not interested.
• Kent Alstad at Dev Connections!
  This should be a scalability show, which are generally interesting, except that I am sick of hearing about "don't use view state", or the fallacy of "scalability means that you can't use convient idioms"
• Tim Sneath and Ian Ellison-Taylor on Windows Past, Present and Future
  That should be interesting.
• Pablo Castro on Astoria
  If I recall correctly, Anders Norås wrote an equivalent for that in a few hours. Not really interested.

I think that I'll leave interpretation of those for the comments, but it looks to me like technology topics are growing very old, very fast.
