I found an interesting YouTube clip from the blog of YV5MM, a Venezuelan radio amateur who I met on the 20 m band tonight:
Some of the presented modes were familiar to me already, since I have tried them: All PSK modes, some MFSK modes, one Olivia QSO (will never forget the chat with an 85 year old English gentleman) and RTTY. As seen in my log, PSK is the most popular digimode...not only for me, but also in general. Soon I'll setup my rig for the legendary JT65 mode: the mode that enables communication well below the noise level. I have played with WSPR already, so I hope it won't be too difficult.
