Hey, just wanted to let you know about a few simple updates to your plugin I was able to make. I added 2 new options to allow removal of hashtags and @replies (includes retweets) from the retrieved Twitter posts.
I have the modified plugin files and uploaded them here: https://www.dropbox.com/s/gvvfuvxeoozs707/twitter-posts-to-blog_udpdate.zip
Check it out and feel free to use the functionality in your plugin.
I had a client who needed this set up for him, so I found your plugin and implemented this small tweak. Felt it was appropriate to let you know.
