Demos with realistic data are really good. They bring software to life, so yes, it is right and good to have believable entries in your career history or customer records rather than bits of Latin, or worse celebrities.
But please don’t cut and paste people’s real data from Linkedin or other social networks and use it in your demo. You are trampling over their privacy and copyright, and you are probably in breach of the Linkedin or Facebook T&Cs too. If you use photos, get permission, even from your employees.
Be careful when you demo social software integration too. People linked with you to be friends, or connections, not demo fodder.
Tread softly, for you tread on my data. Apologies to W.B. Yeats…
