Filter Your Google Plus Stream by Keyword with New Chrome Extension
If filtering your Google+ stream by circles isn't enough for you, check out a new Chrome extension that lets you filter posts in and out of your stream by keywords.
After you download the extension, you'll get a tab where you can input your keywords. The top box is for words you want to exclude, the bottom for words to include [ see above ].
Click the "add" button next to either box and a pop-up box will appear. Enter keywords like "technology" or "cats" (with our without hashtags) and separate them with commas.
