“Delete Post… Delete Post!!!”

If you’ve ever Tweeted while being enraged, inebriated, or a U.S. Congressman, then you know the feeling of wishing you hadn’t posted something online. The folks at Retrevo — a large consumer electronics reviewer and shopping site — recently conducted a study of over 1,000 people to find out what percentage of social media users had posted something they regret. Below are the highlights, but check out the full post, too.

Study Highlights:

– Have you ever posted anything online about yourself that you regretted?
35% of everyone surveyed said yes
54% of respondents under 25 years old said yes
32% of respondents over age 25 said yes

– Of people who posted something online that they regretted:
11% said it didn’t cause any other problems
3% said it ruined their marriage or relationship
6% said it caused problems at work or home
15% said it caused problems, but they were able to remove it.

– Smartphone Owners
51% of iPhone owners have posted something they regretted
43% of Android owners have posted something they regretted
45% of BlackBerry owners have posted something they regretted

– Smartphone owners are 26% more likely to post something they regret.

Retail Sales Down? Try Getting Mobile

Ever since I stepped into the now, so to speak, and got a smartphone, I’ve been much more aware of the need for businesses to have mobile web sites. Even when I’m at home — why not use my Blackberry when my computer is all the way in the other room? (Some call it lazy; I call it resourceful.) At any rate, emarketer.com offers some food for thought that may help your retail sales climb in 2011:

Retailers without a mobile-optimized website may be missing out on sales. According to recent research from mobile and social marketing consultancy Brand Anywhere and Luth Research, 51% of consumers say they are more likely to buy from retailers that have a mobile site. But fewer than 5% of retailers have such a site.

Which retailers would benefit most? According to the study, the product categories most likely to attract mobile-commerce customers include auto dealerships (88% of mobile phone users); auto parts (65%); furniture (62%); florists (61%); jewelry, luggage and leather goods (60%); liquor (50%); sporting goods, books, hobby and music (49%); and clothing and shoes (47%). However, all categories in the study would benefit to some degree.

In February 2010, Multichannel Merchant found nearly 80% of multichannel retailers had no m-commerce presence at all, and April research from eROI showed fewer than one-quarter of marketers overall had a mobile-optimized website.

Ball State Students Not Enthused About Mobile Marketing

A release from eMarketer.com contends that Ball State University students who received ads on their mobile phones were not very enthusiastic about it. (I say if you want people to get jazzed about marketing again — especially on their personal communication devices — then it’s time to bring back The Noid.)

A Ball State University study of a primarily female group of college students found that a majority of them had seen ads on their phones, including 51.2% of smartphone or touchscreen phone users and 61.3% of feature-phone users. Text ads were most prevalent.

Their reactions to ads were highly negative. More than 40% were annoyed to get an ad, compared with just 1.2% who were pleased and 17.6% who were neutral. Even more dramatic, nearly three in 10 said they were less likely to purchase a product after seeing a mobile ad for it. Slightly fewer reported their purchase intent was unchanged, but only a small number said mobile ads encouraged them to purchase.

A substantial minority of respondents (44.3%) would not be induced to receive mobile ads under any circumstances, but 37% were willing to accept them for something free in return. Free ringtones and music were the most popular exchange. In addition, almost two-thirds of all respondents said ads would be OK if they got paid to see them, and the largest segment of that group wanted at least $1 in return for each ad viewed.
