Slideshare is a great service, but I hesitate to recommend it because of the inability to copy text from the slides. This is important for IR presentations where analysts might see something in a slide and want to grab it to paste into a document they’re working on. The download option might give them this functionality, but it’s still a few extra steps.

Other than that, I think Slideshare should be in every IR department’s toolbox, especially for “shows” with more of an entertainment bent where you’re not primarily using it to provide essential, detailed information. I’m thinking of a short company profile or something like that. It’s more work to make a good Slideshare presentation, but the results can be better depending on what your objectives are.

Thanks for bringing this up.

The added benefit of slideshare is that you can add an mp3 recording to your slideshow presentation, and using the tools on their site, synchronize your voice to the slides, turning it into a full-blown presentation.

Here’s an example of a presentation I threw up onto slideshare http://www.slideshare.net/theelusivefish/rss-the-duct-tape-of-web20
