@ShellMonkey To be honest, I totally agree. Again, it boils down to the type of needs you have as a user. I want to have a personal profile where I can post stuff I've written, doing campaigning, share stuff about events I've participated to, and so on. That would be a profile I hand out on business cards and such.
At the same time, I love content/link aggregators, as that is the way of interacting online I find most interesting.
TLDR; I'm still in the search of the best software for my needs.
