Does anyone find the site changing at all ?

Have recently seen some profiles and how they say they are welcoming and to contact , you read the profile and it says welcoming and friendly , but you say hello in the room and find that you get no answer at all so go to the mail system , say hello and explain about yourself and who you are even though if people take time to read it they will get a better understanding of you, and you get ignored , just wonder if any other gents have found this happening a lot more lately.
