** I said I wouldn't post non-English accounts, but I know we have a significant French readership, so if you parle Francais, check out Laurent Evain at ILoveWeb and @iloveweb
If you're an online retailer and read Get Elastic, and would like to be added to our list and start connecting with other retailers via Twitter, drop your name, your website and @twitter-name and I'll add it to this list.
I'm guaranteed to have missed some folks, if I've missed you and you work in or blog about eCommerce, please let me know. I do want to keep this list to Twitterers who work in the eCommerce industry, and only include Twitter feeds in English as we expect this list to grow quite large, to keep it manageable and laser-focused. Also, please only nominate yourself, not other people who should be on the list. Of course, if you feel someone should be on the list, send them a link to this post and encourage them to comment!
