A year ago, I used the StackExchange API to facilitate an analysis of tags on GIS StackExchangeto see what people were talking about on one of the largest and most successful vendor-neutral discussion sites in our industry. In that post, I stated “It would probably be good to revisit this in a year to see how things have changed, if at all.”
Well, a year has passed so I decided to do it again. I used the same scripts and approach I used last time in order to be consistent. Since this is one year later, there is one key caveat. My analysis last year looked at the top 100 tags since the start of the GIS StackExchange site. Since I ran the same query this year, the new results are compounded so what they so are last year’s results plus activity since then. Essentially, you are looking at “that plus this.” The pie chart below shows the breakdown.
