I really like everything about the buzzstream concept and how it's meant to help. I do dislike however a few things that relate mostly to UX/UI and technical difficulties.
I don't like that you have to load unsafe scripts every time you go to buzz bar. if you work for a day in buzz stream and have to go back and forth quite often, it's becoming a bit too repetitive and distracts me from my work.
Buzzbar also doesn't load all the websites, which is probably the main reason I switched back to excel spreadsheets. When I have a list of 200 prospect websites and 30 websites don't load, I have to do it manually and the effort it takes to get out of the app to see it separately then, outreach separately or go back to the app to outreach makes things harder. I doesn't really require much more time, it's just the effort to brake the process that I've established working in buzzstream.
I think another issue is loading time. Sometime it takes a while to move to the next site in buzzbar. I think if the app could load the next website while you're working on the current one, so that you can switch instantly to the next when you're done would make work much easier. I think that extra second often makes a difference.
User interface - I think a better user interface would also help making work easier. It seems a bit text heavy at times and empty at other times. For isntance the ui for previewing a site on the websites tab.
In terms of functionality, one thing I often do is outreach a piece of content to people that linked to other pieces of content or other campaigns. A function in buzzstream that would allow aggregating all websites that already linked to our brand to be targeted for a specific campaign would certainly help this.
