How to display custom twitter posts with the twitter plugin?

Using the twitter plugin, so you can have your twitter posts loaded into the sidebar of your wordpress blog, is there any way of filtering the posts?

For example, I will post technical stuff I’m interested in on twitter, I want that to show up on my blog, but I may also post non-related items, how can I filter these out so they dont show on the blog?

Simple answer would be to have two separate twitter accounts, but then I’d lose followers etc

Depending on the particular Twitter plugin you’re using, you could filter based on the presence of a particular hash tag. Twitter Tracker appears to have the ability to do this when the search is of the form #hashtag from:username.
