Is there an existing object model diagram for ArcObjects? Something that can be printed out as a large poster.

For each namespace in the online help there is a pdf.

I sure think it would be useful if someone made a DeepZoom browser web app for these. I guess the text search would be a bit tricky though.

Ah - I've used these in the past and they've been fairly helpful. I suppose, given the size of each, it's not reasonable to have a single poster covering everything! – Radar Jun 29 '11 at 18:12
Note: Some diagrams don't show everything but focus on the most commonly used objects. – mkennedy Jun 30 '11 at 0:44

If you have the SDK developer kit installed you can find the diagrams here:

C:\Program Files\ArcGIS\DeveloperKit\Diagrams
