Surprised to see Objective C dropping; I wonder why that is? It sure doesn't feel like iOS is getting more web view apps, and with the increased frequency and quality of apps on the App Store in lieu of iOS porting, you'd think it would go up.
Its not really dropping in terms of total questions asked, (obj-C has been sort of constant for about 12 months) but the other tags are increasing. The chart shows a proportion of the top 25 tags.
Ah, fair enough.
I think that highlights a problem with the way the data is presented. jQuery clearly belongs with JavaScript, just as iOS and Objective-C belong together.
