Well, personally, I do not feel the need to adhere to anyone else's business model. And I fail to see how it would be a conflict. My suspicion is that part of eHarmony's business model is luring people from this free site over to the paid side - its a marketing tool.
Thus, I migrated here. And I will not apologize for seeming harsh with some of my opinions - I do believe in self reliance and truly feel that the answers to so many questions are self-evident - if people would only stand up for themselves.
I know I scare off potential dates/mates with this attitude - but would rather wait for the one that can truly hang with me rather than settle.
The problem with trying to meet people on here, is that we are all too far apart, both in terms of geography as well as age.
You might find you have the same opinion on a lot of things with someone, only to look in their Profile, and find they are 20 years older than you, and live completely on the other side of the country.
Yes, I think there have been a couple matches created here, but those are definitely the exceptions, not the rule.
This is why I have no doubt that EH has no fear of EHA taking away business from EH proper.
As to your 2nd part...
Not at all.
Sure, you might offend a couple people, but so what?
I have pretty strong opinions on certain subjects as well, and have no problem voicing them here!
Its your opinion, and as long as its not going out-of-bounds per EHA Forum rules, there is no reason you can't state what you want.
(Its also why we have so many Weight and Height threads)
