Wikipedia is the proof that a free system based on sharing can work and not only does it work, but it works better than the commercial equivalent (at least in my opinion). I don’t think a day goes by that I don’t end up looking something up using this amazing resource.
So, go ahead, support Wikipedia! Do it in whatever way you can, whether financially or by submitting content!*
* I am planning on starting a big Wikipedia-based project in the not too distant future to expand some sections that I care about and I feel are insufficiently developed. If you think you would be interested in helping out, let me know and I’ll give you more details.
If you have 16 minutes to spare… it’s well worth it
