I'm little bit amazed about network hash rate. Sometimes it climbs up to 80 MHash/s but mostly keeps into 20-40 Mhash area. Someone or multipool jumps in and mines couple minutes, brings diff up equivalent to about 80 MHash and then leaves.
Luckily my miner can stop mining it hashrate > X. So my crappy laptop GPU can work when it's easier and doesn't affect my work on laptop

BTW, I'm still keeping, and mining when it's easy. Also, I currently mostly mine solo [101 kHash FTW ]
