A widely used tool for online activism is Salsa - Wired for Change, which integrates a range of online tools, such as email, list and event management, fundraising and more.

However, there are many online apps that do just one of these things, but do it very well. For example, MailChimp for email campaigns, EventBrite for event management, and so on.

What is better? An integrated one-stop-shop like Salsa, or specialised but unconnected apps? Any views out there?

(Note, with the widespread use of APIs, many stand alone tools now integrate. EventBrite and MailChimp for example.)
