With all the hype surrounding social media and "consumer" as the force that defines your brand, you might just think that there is simply no need any longer for traditional sales presentations - you know, the ones you create with PowerPoint slides to tell your story to prospects?

I've created quite a few PowerPoint presentations in my day but I never thought to share them with the wider Web community. As recently as the past 12 months there has been an influx in online services which help facilitate this sharing. Here are two to consider if you want your presentations to receive a little more attention, a lot more traction and way more feedback for those that really make or break your online enterprise.

SlideBurner lets users upload presentation slides from PowerPoint or OpenOffice and converts them into a readable format (flash) for anyone with a web browser. There is currently a 20MB size limit per file but free accounts have a generous storage capacity of 200MB.

Slideshare is another free service for sharing presentations. In addition to PowerPoint and OpenOffice, Slideshare enables users to upload Keynote (for Mac users) or PDF presentations. The service supports a maximum file size of 30MB.

Both communities provide social features such as the ability to create groups, add friends and define presentations with tags. Now while I have not created a PowerPoint in the past few months, I am not familiar with any services provided by Microsoft that would enable the sharing of presentations.

That just might be another Web-based service for Redmond to consider!
