How far back does Momento import historical feed data?
Momento imports as much data from social web services as the provider allows through their API.
Due to Facebook limitations, Momento will only be able to download your last 30 days or 50 statuses, whichever is greater. This limitation was introduced in October 2010.
Please note:
Momento only downloads your status updates from Facebook. Facebook defines a "status update" as being anything you post on your wall that is less than 400 characters and does not contain links or media attachments.
Due to limitations in place by Twitter, Momento can only download your last 3,200 tweets when downloading your past tweets. Until Twitter lift this restriction we cannot download your complete account history.
Gowalla
The Gowalla feed will only import Gowalla check-ins which no longer feature in the most recent version of Gowalla. These are not the same as 'stories' which were introduced in Gowalla v4 (Fall 2011). Unfortunately Gowalla does not yet provide third party access to 'story' data so this information cannot be imported by Momento.
