We at Zapier love Olark. Rarely a day goes by where we don't proclaim to each other our undying love for all that is Olark. Its invaluable. Oddly enough, it is one of the most expensive SaaS apps we pay for, and if they doubled prices, we'd still pay for it.
One humble request: a REST API that just spits out recent conversations. Basically a JSON version of https://www.olark.com/transcripts. Lots of Zapier customers want to send their Olark transcripts into service X, Y, or Z but without that endpoint we can't... [1]
Keep it up guys. :-)
[1] Well, they could use your email feature to send it to our inbound address.. but that isn't intuitive at all.
