The competition between Google and Facebook is about to spill over into plugins for websites: Reportedly launching soon, a comment system ties together Google Plus, and the Internet giant’s search engine and web services.

The Next Web, citing Tech-WD blogger Saud Al-Hawawi, reported that Google announced the comment system, and several other features, at its G Saudi Arabia event earlier this week.

The new comment system will link to Google’s services and websites, with comments indexed in its search engine, and it will be available to third-party sites, according to The Next Web.

The move can be seen as a shot across the bow of Facebook, which has seen its comment interface adopted by millions of third-party websites across the Internet.

Readers: Do you think Google’s new comment system can mount a challenge to Facebook, or is the latter already too deeply entrenched?
