The theologian in me says this person writes about/to god frequently and thus treats words like "you" as a capitalized proper noun so frequently that it's autocorrected.
The rationalist in me says English is not their first language and spends most of their time writing in their native language which may include different noun forms and so is habitual. And given some spacing and punctuation oddities, possibly an older person.
My money is on the rational explanation.
1. What problem are you trying to solve?
2. Who has those problems?
3. Where exactly are they located, both physically or in cyberspace?

Second, based on these answers, do things that don't scale (http://paulgraham.com/ds.html). Actually talk to your customers and figure out what problems they have, and what solutions you can give them. In many user interviews, customers will try to give you solutions but that's not their job, their job is to identify their problems, yours is the job to fix them.
