I wasn't familiar with InboxQ until I saw a reference to a survey they'd done in Entrepreneur's Why Savvy Businesses Field Customer Questions on Twitter. The key quote from the article:
"58 percent of Twitter users said they’re likely to follow businesses that answer their questions on Twitter, and 64 percent said they’d be more likely to make a purchase from a company from which they’ve received an answer to a tweeted query."
The research shows Twitter users like to ask questions, and when they ask companies questions they like to get answers. This pretty clearly illustrates the power of Twitter as a customer support channel.
It will come as no surprise that InboxQ provides a service that "delivers a realtime stream of questions related to your business, products, industry or general interests from Twitter directly to your browser."
Because of our blog, we get sent a lot of surveys to review. To be honest, most are poorly done. But the big problem is not survey methodology, it's how the results are presented. Often the marketing hype and spin of the survey data leads to claims that clearly aren't supportable based on the survey methodology, data and results.
InboxQ&A did not do this. They clearly explained their methodology and results in a ScribD document. It was a non-scientific online survey, which I think is fine given their goals, objectives and market. They don't hype their results and don't make unsubstantiated claims.
Because of this, I would certainly consider becoming a customer of theirs.
