This means that if you start a tweet with @username, only your followers that are also following @username will see it the tweet.

Personally, I like the feature. But some folks don’t. So here’s how you can easily get around it:

When replying to someone, don’t start your tweet with @username.

What I typically have always done when replying to other tweets is:
1. retweet, which copies their tweet.
2. edit out all the extraneous stuff but leave the beef of their tweet.
3. add my reply to the start of their tweet.

So for example.

I’m following @davekozuki.
He sent out this tweet: Building stats module for @teamcoupon

I replied with this: How’s your deal coming along? @davekozuki: Building stats module for @teamcoupon

Therefore all my followers saw it.

Try it!
