Twitter have now updated their API, and requests need to be authorized with a consumer key/secret etc. The software I'm using has been updated in light of this, I'm very impressed with the response time but I have one slight concern. The software allows me to enter multiple sets of keys & secrets to negate the new limits, but has no way of setting one set of keys to only be used with one account. If I keep making API requests for all my accounts using the current setup I am no doubt going to end up using the same set of keys across multiple accounts - is this likely to cause problems with Twitter? I have already emailed the software author to see if he can add the setting I require so hopefully this will be a non-issue, but I'd still like to know in case he says it can't be done.
