I agree about the ask something to ask something issue.
This could/can/does get to the point of getting way too complicated.
These devices are all about making lives simple, and if you ask a question the answer should be given to you, without you needing to remember which skill to ask for first.
There may be times this would be needed, but Alexa could help, by asking you where you want to get the info from.
I think we have UK train timetables and football scores etc skills, really you should be able to ask stuff like this without needing to add in extra speech commands.
I love the Echo, I don't really want to be saying "OK Google" all evening, so I really REALLY home Amazon are going all out to turn this from a great to an amazing product.
