Crossing the line separating Indiana and Illinois sometimes means dealing with different laws and customs. Readers are asked to share ideas for this weekly feature. This week: Bragging.

Both Indiana and Illinois residents rank above the national average when it comes to self-promotional social media posts, according to a new survey that also finds Illinoisians tend to brag about themselves more than Hoosiers.

A questionnaire of social media users found 67 percent of Illinois residents frequently engage in online self-promotion, the sixth-highest state in the nation. That compares to 53 percent of cyber-bragging by Indiana residents, good for 16th out of the 50 states.

The ratings were calculated by asking participants to report how often they post social media messages on potentially self-promotional topics, such as trips to special locations, attendance at memorable events and positive employment news.

California was rated the most braggadocious state, with 77 percent frequently engaging in online self-promotion. Utah won the "most humble" crown at 22 percent.
