1. Make Wikipedia's article simple
Yesterday, I was going through couple of wiki pages like 'theory of relativity', 'Schizophrenia' etc. But everything went over my head. The complex terms use in the article made it difficult to understand. I wanted to know the actual concept, in plain and simple English. If you face the same problem of complicated jargon, then simply replace the en with simple in the url and press enter. For instance -[Before] en.wikipedia.org/wiki/Schizophrenia [After] simple.wikipedia.org/wiki/SchizophreniaThis will load a new wiki page of same article, which is free of all clutter and written in easy understandable English. As simple as that.
2. Better way to save Wiki's PagesÂ
People like to save Wikipedia's article for offline usage. For instance- you may want to read them while traveling in a plane, when you don't have internet access. And hopefully everyone knows how to save pages-  you right-click on a webpage and select the 'save as' option. This will save the page as html fiel in your computer. If you are little advance user, then you will hit CTRL+P on chrome and save the page as PDF file. But Wikipedia's build-in 'save as pdf' (can be found in right side of each wiki article) option is much better. Why ? Well because it solves 2 problem. First the pfd being a single file is more easy to use (not the case if you save webpage as html) and second the output pdf file is free of all clutter and hyperlinks, thus making it print friendly.
If you are doing research and wants to save wikipedia article, then click on the 'create a book' option on left side of the page. With this you can first compile all the articles together and then downloaded their printable version.
3. Quickly lookup a word on Wikipedia
We often find ourself in a situation when, we come across a new word, celebrity, company, place etc. And the first thing we do is we Google it and then click on Wikipedia link. But thats too much work. Right? The solution is using a chrome plugin called Lookup Companion for Wikipedia. After installing the extension, you will notice a small wikipedia symbol on chrome toolbar with a popup search box. Simple copy paste the search term there and it will look it up in wikipedia but inside the same browser. Saves a lot of time.
