Tricki goes live

A short while ago, I blogged about the Tricki, mentioning what I considered an unnecessary subservience to Wikipedia. At the time, Tricki was still pre-live. Recently, Tim Gowers announced that the Tricki is “fully live”, which means that anybody can create a login and add and edit entries.

The Tricki already has a reasonable number of decent articles — an interesting article that I located in group theory is: first pretend that a normal subgroup is trivial. Here’s a link to the list of group theory-related tricki articles. Here is a list of tags that can be used to navigate the tricki.

The concept of the tricki is interesting, and I suspect that a lot of interesting stuff will go on there in the next few months. On the other hand, the main problem I see with the Tricki is that, while it has a lot of useful tricks, there is no easy standard reference it can use for looking up more details of the terms and facts used. The current consensus seems to be to link to Wikipedia, but using only one resource, particularly a resource of dubious value, seems restrictive, particularly since the specific Wikipedia article pointed to may not be particularly good. Consider, for instance, this page where, in the comments, Gowers notes that he “wouldn’t mind being reminded” what a characteristic subgroup is.

Here is what I suggest. For each of the concepts, Tricki should have a short page giving the definition and useful links, and the links from the tricki article pages should point to this short page. This way, article writers can concentrate on writing their articles rather than on defining all the auxiliary concepts involved (particularly in cases where these auxiliary concepts are reasonably standard and known to many of the readers of the article).

The concept page could serve three roles:

  • A concise definition.

  • A list of related tricki articles (this could be automatically generated by backlinks, or manually created and organized).

  • A list of references/weblinks for more details. This list should be carefully curated, and people making such links should actually read the reference being linked to! Wikipedia could, of course, be one of the references typically given, but it need not be the only one.

Why do I think that separate concept pages are important? To take a totally different example, consider newspaper and magazine websites. Many of these websites have their own reference pages on a number of important topics — these reference pages provide a short summary, external links, as well as details of past coverage of the topic. For instance, The New York Times has Times Topic pages on almost all the things it reports on regularly, and its news articles have internal links to these Times Topic pages. While this is partly a tactic to maintain link juice, it also helps provide entry points for people seeking to get information on topics and get an overview of how the NYT has covered the topic. See, for instance, the Times Topic pages on Wikipedia, Twitter, and The Amazon Kindle. It seems to me that despite the presence of Wikipedia pages that may carry a lot more information, these Times Topic pages serve a useful function to readers who are interested in newspaper coverage of the material.

Also, there is something — a lot, in fact — to be said for keeping links largely internal, particularly when building up an extensively cross-referenced body of knowledge, information or insight. Part of Wikipedia’s success can be attributed to its policy of strong internal linking — extensive linking to other Wikipedia pages from within Wikipedia articles.

UPDATE: Gowers has started a forum discussion on some of the issues raised in this blog post.

  1. I’ve started a forum discussion on the issues you raise. It can be found here. It will be interesting to see what people think.

    I just thought that maybe you could please explain me the solvability of Groups and its relation to quintic equations?? (in language and terminology understandable to an 11th std. Student)
