In my previous post I discussed a feature I would like to be implemented by slide-sharing services. I am not going to repeat here all the arguments why slide sharing is useful for scientists. I just want to discuss the present quality of the engines used by these services. I consider here SlideShare, authorSTREAM, SlideBoom and Google Docs from the point of view of scientists. Two years ago I pointed out to you that SlideBoom was by far the best. After two years much could have been changed in a world where nowadays everything on the Internet is about sharing.

If the data are gathererd or produced by a commercial computer program, the developers of that program will try to supply graphing capabilities within the program. Keeping users tied to a program is of high commercial value. So Microsoft’s programs Word and Excel supply plotting facilities, although the capability is so rudimentary that it does not deserve the name.
