We have the same problem, the widget on the side bar of our home page (www.strathpeffervillage.org.uk) now only shows top tweets and omit many of the most important ones related to Strathpeffer.
In our widget code we have toptweets: false, but that no longer works.
We want “all” tweets, including those from us at the website promoting events and activities in the village. Over the last week or so it has failed to show our tweets at all, even though the code has from:StrathVillage and our tweets always include the word Strathpeffer. Obviously we are not yet one of the top (most popular?) tweeters on the subject of our village!
So whatever they’ve done at twitter to the coding they’ve completely broken what was a very good widget. Unless it’s fixed pretty quickly we’ll have to search for an alternative widget which is a shame.
Even the widget creation tool on Twitter’s site now only displays the top tweets instead of all of them. It’s really bad what they’ve done.
