Instagram has amassed more than 30m users since its launch just 18 months ago. It is little surprise, then, that the smartphone photosharing app, which allows users to apply filters to photos taken on their phone and then share them via social networks, including its own, has been the talk of the web for some time.
Interest in the brand has grown further still with the announcement earlier this month that Facebook had acquired the business for a whopping $1bn.
While Instagram's founders may be looking forward to expanding the business with Facebook's backing, the app's passionate users - known as Instagrammers - have been less than enthusiastic about the deal.
Many have publicly vented their frustration and concerns about the acquisition online, with some blogging about fears that Facebook will sell their personal data or 'pollute' their photo streams with ads.
