It's a logo to represent something is a popular topic. The logo is a talk bubble with a 5 pointed star in the middle. The talk bubble its self is a circle with a pointed tail at the bottom left side of the bubble.
This Popular icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 16,000 icons, all in the same style and quality.
