The numerousness of these social networking sites is driving me crazy. I have already started losing track of which all portals I am a member of. Here I try creating a list, with idea about which is for what.
My experience is that it's better to stick to few networks. We can't be active in many networks. It would soon go out of hand if we tried to be active in all in which are signed up.
Blogspot: I use this for blogging general stuff. I started blogging here. So, first mover advantage in my case. I don't have anything particularly good or bad to say about this site.
Sulekha: I use this for blogging creative stuff -- particularly short stories. This is fairly well-read ezine, and widely popular among Indians, world over. Its blogging interface is very sophisticated. Blogs can be put wide number of categories. So, searching for interesting blogs is easier, and so is reaching out to the pertinent audience to your own writing. There's a point system in place, which rates the blogger as per their activity. So, there's this lure of becoming famous.
Orkut: The first proper social networking site I became a member of. It's got the first mover advantage for me. I have over 200 contacts here as of now. I have got back in touch with many many old lost friends though orkut. And also have met people with matching interests (water colouring, cartooning etc.) Its scrapping feature looked crazy and silly in the beginning. But it later became the prime medium of reconnecting with old friends, as I would often bump into old friends while browsing someone's scrapbook.
LinkedIn: This is a very popular professional networking site. Its professional networking and referral system is its novel feature. I have heard that some companies officially demand referrals through LinkedIn.
Minglebox: This is a campus networking site. It's an Indian site. The number of colleges listed in this seems large, but the number of members in each doesn't seem to be too good. IISc has only a little over 20 members. That shows that it hasn't yet taken off. It has got a groovy online chatting facility with your campus mates.
Tagged , Frienster , namesdatabase : These are similar to orkut. Their UI is mostly more sophisticated than orkut's, but they have lost out to orkut on the first mover advantage. Haven't had a chance to explore the features to be able to give a detailed review.
