This is a post about selection of presentation technology and what are the criteria for selecting them, beyond the common features we have come to expect. Here are the criteria to evaluate on:
-free/paid
-ability to import from common file formats
-sharing ability (synchronous control)
--can you control slide progress for viewers?
--can you share desktop? (yes in zohoshow)
--live annotations (digital highligting, digital ink, digital laserpointer)
-asynchronous sharing
--embedding customization control
--embedding cleanliness (zohoshow is a a clear winner here)
--slidecasting (sync with mp3) (slideshare)
-transition ability etc.
-authoring ease
--fidelity of import from existing
--authoring from an RSS feed
--stringing together existing webpages
-ease of use
--interface design
--intuitive distribution of menu items
--sluggishness of the interface
I have not done a comprehensive survey, but found zohoshow come out on top in the case of live sharing and desktop sharing. Google Docs had lovely themes. 280 slides has a nice interface, just like Keynote. Slideroll will create an mpeg for authoring a DVD! Tagslides shows are vulnerable to javascript on pages it shows, which kill the slideshow. If the pages shown on a Tagslide show has javascript to remove the page from frames on another site, that is the end of the slideshow there.
