Mid-week links: Convoq closing, Alliance for Open Competition, O Beverages

A couple Wednesday links...

- When I ran into Chris Herot at the Tech Crunch party last month, he told me he was hoping to sell the collaboration company he co-founded, Convoq. It looks like a sale didn't come together, and Chris has posted some reflections on his blog about the five years he invested in trying to get the start-up off the ground. It's thoughtful writing -- and worthy reading.

- Spark Capital and Bijan Sabet are creating a new group, The Alliance for Open Competition to advocate for eliminating non-compete causes in Massachusetts. They're looking for people to sign on in support of the campaign.

- Xconomy reports on a new start-up from Highland Capital Partners' Consumer Fund, O Beverages. The founder is Tom First, one of the two Toms from Nantucket Nectars. O sounds like a new twist on Vitamin Water, which Coke bought for $4 billion earlier this year.
