During April 2013, eHarmony, like an old car receiving a restyling to simulate a new design, received a facelift, not innovations, only minor changes for an obsolete site. Also went "free to communicate" but every time I had tested it, the paywall appeared with several options to subscribe.
Last March 2012, eHarmony made a mistake and revealed
eHarmony’s secret sauce. (the effectiveness/efficiency of the matching
“99.7% of eHarmony’s members will not be introduced to you (translated from the failed Japanese
site)”, i.e. only 0.3% of members will be shown as a compatible partner
for you; that is the power of eHarmony’s matching algorithm (the

Scientific Paper for the majority (over 90%) of their members.
Actual matching algorithms used by eHarmony,
Chemistry, PlentyOfFish and others, even behavioural recommender systems, can not be improved, they need to be discarded NOW. Because
they are in the range of 3 to 4 prospective mates as selected /
recommended / compatible for dating purposes per 1,000 members screened
in the database. They all 3 are performing the same for serious daters,
with a high percentage of false positives, like gun machines firing
