Someone from Quora can confirm this, but based on what I have observed, I don’t think they are using any third party tool for A/B testing.

I use a tool called Ghostery (browser extension) for this purpose. If the website is using any of the popular third party platforms for web-analytics, tag-management, ad-serving, or A/B testing, Ghostery will be able to detect those. Of course, if you are doing this in-house, it won’t detect anything.

This is what Ghostery detected for Quora:

So, it does not appear that they are using any of the popular third party tools.

Ghostery does detect most third party A/B testing tools, if present:
Optimizely – Analysis by Ghostery
Adobe Digital Marketing (Omniture)
Visual Website Optimiser (Wingify)

New York City. December, 2009: My NYC based friend had to pick me up from one of the metro stations, but I got down at the wrong side of the station. After about 3-4 calls of “Where exactly are you?” and 10 minutes of searching, we were able to find each other. At that time, […]

There is no option to un-filter. Since it’s not clear from your question, whether you are asking from the perspective of a business-owner, review-writer or review-reader, I will cover all three:

However, as a review-writer whose review for a particular business has been filtered (I think you will have to log out to see whether your review has been filtered; your review is not filtered from you), you can do something about it. Build some credibility by writing more reviews, get more friends, do not copy-paste any reviews (not even your own!). You may want to read my answer here: How do the mechanics of Yelp’s review filter work?

If you are an business-owner and your negative reviews are filtered, thank your stars, but go through each of those. There may be no legitimate reason for them getting filtered, except that the reviewer doesn’t have much credibility yet.(see previous para) Unless you are sure that these reviews are from your jealous competitors, take all negative reviews (filtered or unfiltered) as a useful feedback, and try to incorporate that into your operations. However,if it’s your 4* and 5* reviews that are filtered, you can’t do much, except continuing to deliver good service, so that you get more such reviews!

As a review-reader, always pay attention to filtered reviews, especially for businesses with very few unfiltered reviews. (They will ask you to verify your human identity by filling in a re-CAPTCHA) Read them and use your judgement to see which ones feel right, but take them with a pinch of salt. Sometimes, there is a lot of useful information hidden in the filtered ones.

Contd.. from here… Okay! Now, let me put on my Product Manager’s hat! As a Product manager, I would certainly pay heed to the above feature requests. But I also need to think of the features that end-user will not normally think of, and also the ones that will make Facebook some money. I have one […]

Some time back, I had applied to a startup for a Strategy intern position, and as a part of application, I had to answer some interesting questions. One of them included what would I like to see in Facebook. I didn’t want to delay the application, and submitted whatever I could think of in 30-40 […]

“Segment! Segment!! Segment!!! Never work on market level averages. Average distort reality!”  A very common advice in the B-school especially for those who have taken Market Intelligence or are preparing for consulting case interviews. But it is surprising to see how often the real world businesses completely ignore it. Not sure whether they are not […]
