Over the next few months this feature will be added to http://tweetminer.net - one way or another.

Of course it would be great to use a service like this to do the heavy lifting rather than code it myself...

But why would I pay $400 per month for 500 searches per month... when

a) 500 searches per month cost of $4,800 per year

b) 500 searches wouldn't be enough to service my target user-base of 10,000 users.

c) I could roll my own in less than 2 weeks

To be viable for an app developer like myself - the pricing structure would need to make it impossible for me to even consider rolling my own.

BTW - I'm not trying to dis the service, looks nice, just pointing out the pricing structure seems to be wayyyy too high
