What?

So is it true, you really can't read thoughts?

HAHA!!! OMG that's a good answer. I get those kind of questions in my mailbox some times. Brilliant.

Stop being smart and they stop asking questions.

Does your product include a few bullet-proof simple real world examples or do the customers just try to implement it using the dribs and drabs of information they get from the blog?

Ayende,

I sure hope this wasn't a customer, I respect your talents and your software but you may want to take a step back when it comes to customer service. It is just as important, if not more important in some respects as the quality of the software you deliver.

Don't get me wrong, I hate it when people email me clear out of the blue with random programming questions. Its very easy to be condescending and arrogant, its extremely taxing and difficult to be helpful and understanding to their problems. Thats the real challenge in business!

Also don't expect to get the information you need from a customer, on the first try or perhaps ever!

"Am i missing something"

Yes.

Really liked the opening..

Who are you?

and a strong finish with the debugging advice. Haven'd used INotifyCollectionChanged extensively, but your physic advice is right on.

Wonder the person replied back?

Also missing: punctuation.

It was probably someone who stumbled on the blog and was trying to be given the tools/knowledge to do their job instead of being able to do the work themselves.

I see it all the time, although usually it's somewhere in the comments of a blog and not an actual email; a poorly-worded and vague comment that is along the lines of: "i am working on a similar problem please give me the code u used to fix this problem" and nothing else provided - obviously someone trying to pass themselves off as a programmer but without any clue what they're doing.

I would not have even replied.

I'd have probably answered

"Why would I care?"

Sometimes it is just for fun: How many smart as..s will be answering some silly question?

And I have joined you all with my post

@Mark Petrov that would be quite arrogant. :)
