In fact, I followed it the following year with an article explaining the choice between Buskerfest Toronto and an Ashkenaz festival (which returns to Harbourfront in August 2014, thanks for asking).
So why add "How to Find the 2013 Toronto Buskerfest" this year? My biggest motivation was that they changed the venue; and I'd explained how to get to Buskerfest Toronto in the previous articles.
While I care that people may go to the wrong location because they read my old article this year, what also matters is my reputation for accuracy.
Three More Annual Events in Toronto
"Richard III, Afro Caribbean or Chinatown in Toronto for 2013" covers a 2013 production by Shakespeare in the Ruff, plus the Afro Caribbean Festival in Scarborough and the annual Chinatown Festival in Toronto.
While these annual summer events have stayed in their traditional locations, I still provide street intersection and public transit advice. Some readers may be tourists. Even a Toronto native might not be familiar with locations such as Withrow Park; or realize which Chinatown hosts this particular festival.
One Double Repetitive Writing Tip
Specifically, the title of my 2011 article, "How to Find Toronto Buskerfest 2011", is far too similar to my 2013 article. It's especially glaring when one article links to the other.
So do better than I did this time, when you revisit a topic. Take the time to ensure you are not plagiarizing your own title or opening line. It might be the best in the world; but change something so your readers won't think you're in a rut.
My second writing tip is to revisit old articles if you realize they have become outdated. Check what I did in the earlier article(s): I explicitly say that the Buskerfest Toronto location changed in 2013. I also give a link to my recent article.
It's always possible that people will find the older article. In fact, if you can write about "evergreen" topics, you get readers over the long term.
But when important details change, you should at least advise your readers to check a more up-to-date source; perhaps your new article!
Thanks for reading about Buskerfest Toronto 2013.
