For those of you who have Twitter for Android, you’ll start seeing a change in the next few weeks.

As you may well be aware of, the website version of Twitter has seen promoted Tweets showing up in Timeline. The mobile version of Twitter has been safe from that until now. Promoted Tweets will now show up on the mobile version of Twitter for Android and you’ll first start seeing promoted tweets from those that you follow, but in the months that follow, you’ll see tweets from other ad-supported accounts.

It remains uncertain whether Twitter for iPad will get the same treatment, but it makes us wonder: how many more of these ad-related changes will Twitter have for us?
