SlideShare is a slide hosting service: it allow users to upload, view, comment, and share slideshows created with presentation programs.
When visiting the site you are welcomed with a short description of SlideShare's abilities: 'Upload and share your PowerPoint & Keynote presentations, Word &PDF documents on SlideShare. Add audio to make a webinar. Capture leads with your presentations.' So SlideShare does not simply enable users to upload slides, it supports also other formats (including OpenOffice - a great advantage in my view). Additionally, users can add audio to their presentations, embed YouTube Videos inside presentations and make use of event functionality to send conference invites, etc.
SlideShare enables 100 MB per presentation, and this is useful when making an extensive presentation with many pictures. Documents can be made public, remain private or can be accessible only to those, who the author identifies as friends : when registration is completed, user is asked if he would like to import friends from existing email addresses, so SlideShare is obviously intended to works also as a social networking site.
After uploading a presentation to this slide hosting service, I had to to wait a while in order for the presentation to load completely. Then I could take a look at my presentation and the first thing I noticed was, that the site looks a lot like YouTube: the presentation on the left and on the right user information and presentation description. Beneath, thiere is a 'related presentations' section and under the presentation part are links to different social networking sites, blog platforms, etc. and a 'comment' section. I like the fact that a HTML code, which allows embedding it to a web site or blog, is available and situated in a visible spot.
Presentations are easy to manage and the site itself is easy to use. SlideShare users can also join groups by interests and debate about any subject they are interested in.
I like this tool, because it is user-friendly and really easy to use, there is no need for tutorials on the basic operations, but I intend to look deeper into its functions. Unfortunately, I can't make any comparisons yet, since this is the only slide hosting service I ever tried.
Well, here is the the result of my 'curiosity': (please note that this presentation of collaborative project is still in progress so this is a working version of my part only)
