One of the weaknesses of LingQ is that new members do not pick up all the functionality of the site very quickly, I propose that this is may be your case. I will address some of your statements one at a time.
“On livemocha I could never make other hear my speaking exercises - the recording option never works for me. Here you need to pay to try it. The only way I will be sure it works here would be to be able to record my speaking in mp3 and upload the file to my tutor.”
I am not sure what you mean. If you want to add something to the library, you record it, transcribe it and import it. If you need a tutor you arrange a time for speaking or you send some writing for correction.
"About the mp3 and the transcribe - I have already a lot of data - all free from the internet. Lingq is one more source for that - a lot of what is available here is available elsewhere - often in a more easy way and with a best preview on the technical quality of recording and difficulty of language. And with a best preview on the quantity of data available (I do not mean the size of the file but the number of them). "
I invite you to share your sources, we can add them to a database of copyrighted audio and matching transcripts.
"We pay here to use the lingq (the vocabulary learning tool) well I have free softwares which do the same - offline "
Could you share this resource so we can see if it is equivalent in connectivity to dictionaries, ability to pick up surrounding phrases, highlighting capability across texts, ability to reference examples across texts, etc ?
'We also pay for tutor but I do not know the quality of the tutors. For what I read from tutors in my native language - their quality is not worthy the price."
Could you give examples? Or if you feel it is too sensitive in a public forum, feel free to email examples to the people who operate the site.
"I would like to see statistic on the community how many people are native speakers in my target languages - how many of them target my native language - how many are active members and so on… "
You can get that info through the Friend search function. It is not aggregated on your personal profile page, but I don’t think that is important to a huge number of people.
"I get an email telling me one member puts me as her friend but I do not see anything on the site ? Now I take her as a friend but what is the advantage ? "
I agree. That should be fixed.
"Do you pay something to website owners where you take material from. I know they puts their matrerial for free but I am about sure you are not supposed to make money out of what they offer for free. I know we pay for all the work beside but all your work with the lingq would have no (or a lot less) value without the material of other websites. You do not pay money to members who import material either that they takes from the internet or that they produce of their own. "
If I understand you correctly, you are saying that LingQ itself just provides a platform and doesn’t produce content, instead using member created content or importing non copyrighted content. First, LingQ has produced a huge amount of original content. Second, the platform needs programmers to maintain and build it, which cost money. To see the value of this platform you have to appreciate the functionality of it.
