Ha....your right.....unfortunately people want email to be instant.......

In most mid sized companies 25-100......email is used a lot for collaborating with each other....sending files....sending requests.....updates...etc.
They send you an email.....call you 5 mins later...did you receive my email? Its urgent.......can you please do it now?
Of course, if its someone important in the company....you can't say...oh its not time to check my email yet...so I will get to it......plus it might actually be urgent.....

So yes..people now expect email to be instant.....like a task listing....new tasks come in......you check.....except...you can do a lot of other non-useful things with email.

Yes.....all the above this is because of poor planning probably....no scheduling....task management....proper systems...policies...etc.....but the problem can be solved by good Business Flow/Task Flow systems. But cost is prohibitively high for smaller companies to have good business flow control systems that can replace email.

Also....many times...such systems are very complex and harder to use as well......so the benefit of not using email might be lost.....

Email can be replaced if
1) The whole business has an excellent business process flow control system that encompasses all processes where by all task are entered, tracked and traced.
2) Such system is scalable
3) Such system is easy to use

If we have the above...email use can be limited...and possibly eliminated......with use of other technologies....
Client communications would then just be a task in the process chain.....

Now....who can make such systems for businesses.....easy..simple...cheap...bug free.....no downtime.....

Utopia.

I think money for buildings should be spent on creating more content.

KA's biggest strength is that it is online, ie, easily accessible, content easily creatable, no barriers to entry accept internet. Videos should be downloadable....and this will solve that issue.

I don't mind his teaching methods but some of his language may be too advanced for for younger kids....so money should be spent on creating more suitable content for a wider range of topics. Not just for the reason I mentioned but there is only so much he can do....and he has surely done a lot......

Open it up for anyone to be able to create...pay people not to create but to moderate other creations....this way...you allow anyone to use the skills to create and moderators can make sure it is appropriate and passes QA.

Schools should use KA and integrate it into their curriculum instead of KA starting their own school
Summers camps can he held anywhere using KA.

I agree with the other expenses, ie CMS, etc since making content creation and management easy is a big deal and will allow for other content creators to upload and mange content properly. I would go with integrating an elearning system with it for all the courses. They already have something for some but not all courses.
Teachers form anywhere should be able to integrate with the elearning system and keep track of students activities, thsi way you are empowering many teachers as opposed to only KA teachers/students.
