So does MJ just have a number in the title of almost all of their articles or are MJ page viewers just attracted to titles with a number in them?
No. People just tend to love their lists. There are +20 times as many MJ articles on topics like the December 2014 Construction Update, Should Chains Receive Tax Money To Open In Downtown, A Cheap Solution To Jax's Convention Center Problem, and LaVilla: Rise & Fall of a Great Black Neighborhood, etc. They just don't go viral with the general public, which is why most don't sniff the top 25 list.
For example, "Jax Native Tyler Shields on the BlackList at Sundance" pulled in 1028 views and "New Avondale Restaurant Proposed: Not Everyone Happy pulled in 12,157 views. Both are more informative than "10 Things Jaxsons Have To Explain To Out-Of-Towners" but that one has 105,361 views so far. I guess that's the reality of the community we live in today.
