Hi,
I see a large proliferation everywhere ... and while it is nice ... I think there is too much "novelty" ... and too many people are 10 years behind the times.
All in all, having your own website is still the best ... since My Space and all those have limitations ... that eventually will slow you down ... and make things cluttered ... I personally do not like to be amidst ... "everyone else" ... since I am NOT everyone else.
And for you to make your mark ... you can NOT be everyone else. It's that simple.
I'm not sure that My Space, Soundclick, or any of those folks are good enough for you to make ... 3 to 4k per month, so you have enough money to buy food and pay rent and take the girlfriend out once in a while! Or buy her something nice once in a while ...
The only bad thing here ... is that too many companies that do Hosting are really screwed up ... I would always have 3 or 4 accounts that are "investments" ... but this is where trust comes in ... but if you have a piece of paper with a tax return ... the trust issue is not on your side ... it's on theirs ... and if they do not know the difference in investing ... don't bother with them.
But you have to have a return as such, for example, so that people can say ... he's serious, isn't he? ... and you have a chance ... otherwise it's like the majority of the stuff on YouTube and all these sites ... it's all the same and everyone sounds the same and everything is a mom and pop jack cheese song ... and I don't think that I have found enough of these to count on more than one hand ... that are worth the attention!
So ... let me ask you ... where do you want to be?
But don't expect people to do you favors ... the only favor you gonna get is when the numbers start flowing through your hand like nuts and sand ... everyone will want your signature then ... and you can pick and choose!
