I use chrome on my android and generally I can view the site fine. I do get lags with 'likes'. I also have an issue with slowly loading replies as other have mentioned above.
I have another issue, but this may just be my phone, typing messages from my mobile is very unreliable. The auto correct posts very crazy words even things like 'clairrrtyytytaaw' -- which makes no sense. I type the correct 'clarity' on my phone.. and it turns into gibberish. It is very difficult and time consuming to reply correct and coherent messages from my phone.. and takes me a lot longer to go through and correct the odd words. I have no idea why this happens on this site. I use the same typing feature for all of my mobile's sms, apps, emails, etc.
