Weird side point, but I'd be really interested to hear how people weight the importance of Wikipedia text vs media vs history. For me the first is 99% of the point, but clearly others feel differently.
When I saw that the film Defiance was based on a interesting-sounding real set of events, I looked at them on Wikipedia. The history and talk pages had an ongoing edit war with a sizable number of commentators who appeared to feel that the Bielskis should be treated as criminals and murderers rather than fêted as heroes, due to their killing of local Nazi sympathisers.
If you just stuck to the hashed-out Wikipedia page that was current, you'd be completely oblivious to the whole controversy.
Yeah, you're probably right. But the history can be really important on certain pages. https://news.ycombinator.com/item?id=1671756 And images can make some of the math articles useful since they are too-often dense pages of formulas.
I find that Wikipedia's text heavy presentation disappointing especially considering that the articles are almost exclusively what I would consider extremely terse. It's like the worst of both worlds.
I remember reading about Xowa and there was stated that English wikipedia requires 25GB and images additional ~80GB which you can all download and access offline with Xowa. Considering there are 128GB SD and micro SDXC cards readily available for ~$100... that's actually amazing.
