One suggestion that would greatly improve the usefulness of the data, so as to accommodate for the relative sparsity of the data, is to limit industry to a selection of 20 or so categories, rather than allowing participants to enter it free-form. For example, I'm seeing 'Telecommunications', 'Telecom', 'IT & Telecommunications' split out separately. Also, 'Healthcare' and 'Healtcare'. There are also several variations of Technology.
