Just looked at all the items on the wiki under Category:Web Applications. Many of the programs didn’t say squat about what their purpose is. Even some of the “overviews” are overviews of installation, not the program. Can a decent overview be made a requirement or strong suggestion.
That a great suggestion! It’s worth noting, however, that much of the wiki is “user-contributed” and maintained. You are welcome to jump in yourself and add anything you feel might be helpful, and your help with that would be most appreciated.
There is a long list that many of us “wiki gnomes” have to work our way through to improve the wiki, and many of these types of things are on it.
In the mean time, Google can generally give you a good idea of what any of those programs are about, and many of those wiki pages also have external links to the home pages of the applications themselves, and that might be worth a look.
