I was digging up some 2013 web stats for someone else and came up with two quick stats that might be of interest to some:
Averaged over the year (2013), our digital exhibit and collection sites saw around 100 visits per hour, while our main web site saw around 280 visits per hour.
Or if you prefer, digitization sites saw ~2,400 visits/day, while the web site saw ~6700 visits per day.
No idea how this compares to other places, but good to know if only as a benchmark.
If you have a first-generation iPhone 4 (i.e. running the A4 processor) and are considering upgrading to iOS 7 my recommendation would be to hold off until you have a new phone with the processing power to handle it.
After upgrading to iOS 7 after a few weeks ago, I can safely say that while the phone remains usable, it is a lot more sluggish even for basic operations. Sometimes the lag is barely noticeable, sometimes maddenly so.
It wasn’t too hard to get used to the changes in the interface, but I while the UI for iOS 7 is different, I’m not sure it is any better. Learning the new way of doing things felt like climbing a hill to get back to where I was. Except that everything is a bit slower.
So aside from getting to play with the new UI, in my opinion there is no upside to upgrading a first-gen iPhone 4 to iOS 7.
Update (Mar 10): This Ars Technica article takes a more detailed look at running iOS7 on an iPhone 4 and more or less jives with what I’ve experienced myself.
