Which topics are the most popular at the BioStar bioinformatics Q&A site?
One source of data is the tags used for questions. Tags are somewhat arbitrary of course, but fortunately BioStar has quite an active community, so “bad” tags are usually edited to improve them. Hint: if your question is “How to find SNPs”, then tagging it with “how, to, find, snps” won’t win you any admirers.
OK: we’re going to grab the tags then use a bunch of R packages (XML, wordcloud and ggplot2) to take a quick look.
