There are several things on the Internet that help us a lot but that we take for granted. One of them is Wikipedia.
Apart from being one of the best examples of why the Internet is changing the world (for the better!), Wikipedia is also one of the most useful websites around. I probably land on it at least once a day, and the information is always accurate. On top of that there are no ads around, and the entity that owns/manages it is a non-profit organization.
Neat huh?
So how does Wikipedia covers its costs? With donations from its users. Once in a while they run low on funds, and they need to display a message on top of the website asking for some help. If you go to the website right now you’ll notice such a message.
When I saw it yesterday I donated $20 right away, for all the reasons above. You can use Paypal for the donation, so if you have some funds there I would encourage you to support them as well.
If donating is not an option you can always help Wikipedia in other ways. One of them is to write about it on your blog, and another yet is to join as an editor to write and edit articles inside your areas of expertise.
