We actually want to move away (as much as possible) from stories that just load
a page. Could we select a few of these and make them into browse:* stories?

[ssid, 2017/04/04 03:43:48]

Moved a few stories. Thanks! Some of these don't fit in browsing stories, we
just want to load the page and it's good enough, like irctc and cric buzz.

One thing about these wait is if the page misbehaves, you won't know. Can you do
s.t like:
WaiForElementToBeInViewport(..)

[ssid, 2017/04/04 03:43:48]

I actually added these waits as a user behavior rather than waiting for page to
load. I see there are other Wait calls in searching_stories which simulate user
reading the page.
The waitForElement in the first line waits for the actual map surface. These
actions will only move the surface around. So, I am not waiting for any specific
element here.

[perezju, 2017/04/04 09:23:38]

I would suggest to add some comments to any remaining waits to document that
this is the intention.
