For what it's worth - I use Wikipedia for two purposes...

- As a convenient "point of entry" on the web for a person or topic I want to know more about. You can usually judge from the length and style of the article whether or not it is well done and/or reliable or complete. Then, it is also useful as a pointer to what is out there in other places (source used, external links, etc.) - so that you can check for yourself whether the information in the article is correct, if you wish.

- As a place to collate useful information I have found, that is not yet on Wikipedia, for the benefit of others. Hence my interest in contributing new articles, or expansion of existing ones. E.g. if I am searching WP for information that I think should be there, but isn't, I will add it so as to make others' online searching easier. That's it in a nutshell.

For example, I went to Wikipedia looking for information on Isla Cameron (prominent 1950s-1960s folk artist, but little known today). There was not a lot there, so I researched some more, and added it to the article. Now it's not bad: https://en.wikipedia.org/wiki/Isla_Cameron... The good thing about Wikipedia is that if others do the same, it can get better again (or more complete, or whatever). So in general (as you can probably tell), I think Wikipedia is A Good Thing - not perfect or complete by any means, but a good deal better than the old pre-internet days.

Just my 2 cents worth of course.
